                       System reasons

                       Usage Note: "MAP" code does not indicate the semantic fidelity of the transformed content.

                    To indicate semantic fidelity for maps of HL7 to other code systems, this security alteration integrity observation may be further specified using an Act valued with Value Set: MapRelationship (2.16.840.1.113883.1.11.11052).

                    Semantic fidelity of the mapped IT Resource may also be indicated using a SecurityIntegrityConfidenceObservation.

                       Usage Note: "MASKED" may be used, per applicable policy, as a flag to indicate to a user or receiver that some portion of an IT resource has been further encrypted, and may be accessed only by an authorized user or receiver to which a decryption key is provided.

                       Rationale: Personal data which has been processed to make it impossible to know whose data it is. Used particularly for secondary use of health data. In some cases, it may be possible for authorized individuals to restore the identity of the individual, e.g.,for public health case management.  Based on ISO/TS 25237:2008 Health informatics—Pseudonymization

                       Usage Note: "REDACTED" may be used, per applicable policy, as a flag to indicate to a user or receiver that some portion of an IT resource has filtered and not included in the content accessed or received.

                       Usage Note: This is not suitable to be used when information is removed for security reasons - see the code REDACTED for this use.

                       Usage Note: "SYNTAC" code does not indicate the syntactical correctness of the syntactically transformed IT resource.

                       Usage Note: "TRSLT" does not indicate the fidelity of the translation or the languages translated.

                    The fidelity of the IT Resource translation may be indicated using a SecurityIntegrityConfidenceObservation.

                    To indicate languages, use the Value Set:HumanLanguage (2.16.840.1.113883.1.11.11526)

                       Usage Note: When this code is used, expectation is that the system has removed historical versions of the data that falls outside the time period deemed to be the effective time of the applicable version.

                       Rationale: This definition is intended to align with the ISO 22600-2 3.3.19 definition of cryptographic checkvalue: Information which is derived by performing a cryptographic transformation (see cryptography) on the data unit.  The derivation of the checkvalue may be performed in one or more steps and is a result of a mathematical function of the key and a data unit. It is usually used to check the integrity of a data unit.

                    
                       Examples: 
                    

                    
                       SHA-1
                       SHA-2 (Secure Hash Algorithm)

                       Rationale: This definition is intended to align with the ISO 22600-2 3.3.26 definition of digital signature:  Data appended to, or a cryptographic transformation (see cryptography) of, a data unit that allows a recipient of the data unit to prove the source and integrity of the data unit and protect against forgery e.g., by the recipient.

                    For example, a Certificate Policy (CP), which is a named set of rules that indicates the applicability of a certificate to a particular community and/or class of application with common security requirements.  A particular Certificate Policy might indicate the applicability of a type of certificate to the authentication of electronic data interchange transactions for the trading of goods within a given price range.  Another example is Cross Certification with Federal Bridge.

                    The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. [OMB M-04-04 E-Authentication Guidance for Federal Agencies] 

                    Low authentication level of assurance indicates that the relying party may have little or no confidence in the asserted identity's validity. Level 1 requires little or no confidence in the asserted identity. No identity proofing is required at this level, but the authentication mechanism should provide some assurance that the same claimant is accessing the protected transaction or data. A wide range of available authentication technologies can be employed and any of the token methods of Levels 2, 3, or 4, including Personal Identification Numbers (PINs), may be used. To be authenticated, the claimant must prove control of the token through a secure authentication protocol. At Level 1, long-term shared authentication secrets may be revealed to verifiers.  Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol.   [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]

[OMB M-04-04 E-Authentication Guidance for Federal Agencies]

                    Basic authentication level of assurance indicates that the relying party may have some confidence in the asserted identity's validity. Level 2 requires confidence that the asserted identity is accurate. Level 2 provides for single-factor remote network authentication, including identity-proofing requirements for presentation of identifying materials or information. A wide range of available authentication technologies can be employed, including any of the token methods of Levels 3 or 4, as well as passwords. Successful authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token.  Eavesdropper, replay, and online guessing attacks are prevented.

[OMB M-04-04 E-Authentication Guidance for Federal Agencies] 

                    Medium authentication level of assurance indicates that the relying party may have high confidence in the asserted identity's validity.  Level 3 is appropriate for transactions that need high confidence in the accuracy of the asserted identity. Level 3 provides multifactor remote network authentication. At this level, identity-proofing procedures require verification of identifying materials and information. Authentication is based on proof of possession of a key or password through a cryptographic protocol. Cryptographic strength mechanisms should protect the primary authentication token (a cryptographic key) against compromise by the protocol threats, including eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks. A minimum of two authentication factors is required. Three kinds of tokens may be used:

                    
                       "soft" cryptographic token, which has the key stored on a general-purpose computer, 
                       "hard" cryptographic token, which has the key stored on a special hardware device, and 
                       "one-time password" device token, which has symmetric key stored on a personal hardware device that is a cryptographic module validated at FIPS 140-2 Level 1 or higher. Validation testing of cryptographic modules and algorithms for conformance to Federal Information Processing Standard (FIPS) 140-2, Security Requirements for Cryptographic Modules, is managed by NIST.
                    
                    Authentication requires that the claimant prove control of the token through a secure authentication protocol. The token must be unlocked with a password or biometric representation, or a password must be used in a secure authentication protocol, to establish two-factor authentication. Long-term shared authentication secrets, if used, are never revealed to any party except the claimant and verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent verifiers by the CSP. Approved cryptographic techniques are used for all operations.  Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol.    [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]

                    The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. [OMB M-04-04 E-Authentication Guidance for Federal Agencies]

                    High authentication level of assurance indicates that the relying party may have very high confidence in the asserted identity's validity. Level 4 is for transactions that need very high confidence in the accuracy of the asserted identity. Level 4 provides the highest practical assurance of remote network authentication. Authentication is based on proof of possession of a key through a cryptographic protocol. This level is similar to Level 3 except that only “hard� cryptographic tokens are allowed, cryptographic module validation requirements are strengthened, and subsequent critical data transfers must be authenticated via a key that is bound to the authentication process. The token should be a hardware cryptographic module validated at FIPS 140-2 Level 2 or higher overall with at least FIPS 140-2 Level 3 physical security. This level requires a physical token, which cannot readily be copied, and operator authentication at Level 2 and higher, and ensures good, two-factor remote authentication.

                    Level 4 requires strong cryptographic authentication of all parties and all sensitive data transfers between the parties. Either public key or symmetric key technology may be used. Authentication requires that the claimant prove through a secure authentication protocol that the claimant controls the token. Eavesdropper, replay, online guessing, verifier impersonation, and man-in-the-middle attacks are prevented. Long-term shared authentication secrets, if used, are never revealed to any party except the claimant and verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent verifiers by the CSP. Strong approved cryptographic techniques are used for all operations. All sensitive data transfers are cryptographically authenticated using keys bound to the authentication process.   [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]

                    Low authentication process level of assurance indicates that (1) long-term shared authentication secrets may be revealed to verifiers; and (2) assertions and assertion references require protection from manufacture/modification and reuse attacks.  [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]

                    Basic authentication process level of assurance indicates that long-term shared authentication secrets are never revealed to any other party except Credential Service Provider (CSP).  Sessions (temporary) shared secrets may be provided to independent verifiers by CSP. Long-term shared authentication secrets, if used, are never revealed to any other party except Verifiers operated by the Credential Service Provider (CSP); however, session (temporary) shared secrets may be provided to independent Verifiers by the CSP. In addition to Level 1 requirements, assertions are resistant to disclosure, redirection, capture and substitution attacks. Approved cryptographic techniques are required.  [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]

                    Medium authentication process level of assurance indicates that the token can be unlocked with password, biometric, or uses a secure multi-token authentication protocol to establish two-factor authentication.  Long-term shared authentication secrets are never revealed to any party except the Claimant and Credential Service Provider (CSP).

                    Authentication requires that the Claimant prove, through a secure authentication protocol, that he or she controls the token. The Claimant unlocks the token with a password or biometric, or uses a secure multi-token authentication protocol to establish two-factor authentication (through proof of possession of a physical or software token in combination with some memorized secret knowledge). Long-term shared authentication secrets, if used, are never revealed to any party except the Claimant and Verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent Verifiers by the CSP. In addition to Level 2 requirements, assertions are protected against repudiation by the Verifier.

                    High authentication process level of assurance indicates all sensitive data transfer are cryptographically authenticated using keys bound to the authentication process.  Level 4 requires strong cryptographic authentication of all communicating parties and all sensitive data transfers between the parties. Either public key or symmetric key technology may be used. Authentication requires that the Claimant prove through a secure authentication protocol that he or she controls the token. All protocol threats at Level 3 are required to be prevented at Level 4. Protocols shall also be strongly resistant to man-in-the-middle attacks. Long-term shared authentication secrets, if used, are never revealed to any party except the Claimant and Verifiers operated directly by the CSP; however, session (temporary) shared secrets may be provided to independent Verifiers by the CSP.
