Abstract security metadata observation values used to indicate mechanism used for authorized alteration of an IT resource (data, information object, service, or system capability)

Security metadata observation values used to indicate the use of a more abstract version of the content, e.g., replacing exact value of an age or date field with a range, or remove the left digits of a credit card number or SSN.

Security metadata observation values used to indicate the use of an algorithmic combination of actual values with the result of an aggregate function, e.g., average, sum, or count in order to limit disclosure of an IT resource (data, information object, service, or system capability) to the minimum necessary.

Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability) by used to indicate the mechanism by which software systems can strip portions of the resource that could allow the identification of the source of the information or the information subject. No key to relink the data is retained.

Security metadata observation value used to indicate that the IT resource semantic content has been transformed from one encoding to another.

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.

Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability) by indicating the mechanism by which software systems can make data unintelligible (that is, as unreadable and unusable by algorithmically transforming plaintext into ciphertext) such that it can only be accessed or used by authorized users. An authorized user may be provided a key to decrypt per license or "shared secret".

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.

Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability), by indicating the mechanism by which software systems can strip portions of the resource that could allow the identification of the source of the information or the information subject. Custodian may retain a key to relink data necessary to reidentify the information subject.

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

Security metadata observation value used to indicate the mechanism by which software systems can filter an IT resource (data, information object, service, or system capability) to remove any portion of the resource that is not authorized to be access, used, or disclosed.

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.

Metadata observation used to indicate that some information has been removed from the source object when the view this object contains was constructed because of configuration options when the view was created. The content may not be suitable for use as the basis of a record update

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

Security metadata observation value used to indicate that the IT resource syntax has been transformed from one syntactical representation to another.

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

Security metadata observation value used to indicate that the IT resource has been translated from one human language to another.

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)

Security metadata observation value conveying the alteration integrity of an IT resource (data, information object, service, or system capability) which indicates that the resource only retains versions of an IT resource for access and use per applicable policy

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.

Abstract security observation values used to indicate data integrity metadata.

Examples: Codes conveying the mechanism used to preserve the accuracy and consistency of an IT resource such as a digital signature and a cryptographic hash function.

Security metadata observation value used to indicate the mechanism by which software systems can establish that data was not modified in transit.

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)

Security metadata observation value used to indicate the mechanism by which software systems use digital signature to establish that data has not been modified.

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.
