What is ISO 14533-4 - PoE Attributes in long term signature about?
ISO 14533-4 specifies the elements defined in the international standards of ISO/ITU-T, ETSI and IETF RFC that enable at least a proof of existence of data objects and digital signatures and the preservation of the validity status of digital signatures over a long period of time used in validation.
ISO 14533-4 provides the definitions of the proof of existence (PoE) attributes and clarification of the usage of (external) PoE objects, with digital signatures and trusted time values, which have already existed and can be used by the proof of existence attributes pointing to proof of existence objects used in long term signature validation or preservation.
ISO 14533-4 specifies the proof of existence attribute as an object which provides a reference between optional data objects and the trusted evidence of at least one property of the data object or a set of data objects, especially the integrity, status, type of data object or type of interpretation at a specific time interval or at the date and time.
Who is ISO 14533-4 - PoE Attributes in long term signature for?
ISO 14533-4 on PoE Attributes in long term signature is useful for:
- E-commerce companies
- Organizations and industries that use electronic signatures (i.e., Accounting and tax, financial services sectors, marketing industry, the legal industry, etc)
- IT firms / software programmers
- Legal entities / government bodies dealing with electronic signatures
Why should you use ISO 14533-4 - PoE Attributes in long term signature?
ISO 14533-4 provides you with detailed information associated with the analysis, selection and implementation of procedures associated with long term signatures. The development of ISO 14533-4 is a result of organizational requests to receive information of already existing objects defined in technology standards, technical reports, and industry best practices for electronic signatures verifiable for a long term.
ISO 14533-4 ensures the interoperability of implementations with respect to long term signatures that make electronic signatures verifiable for a long term. This document clarifies conditions used in the validation procedure to provide a complete and unalterable result.
ISO 14533-4 lists the ASN.1 module assigned to the attributes pointing to external proof of existence objects used in long term signature formats. ISO 14533-4 guidelines provide clarity on digital signature procedures to industry entities.
