Metatime: a timestamp token solution for your documents

Demonstrate when transactions took place or documents were archived with a timestamp solution

Organizations moving to paperless exchanges, whether for internal communications or for relationships with partners or customers, may be required to demonstrate that certain transactions or actions occurred before a given date and time.

The use of a time-stamp token associated with the document provides an element of proof of a digital transaction’s date and anteriority. This includes a signed piece of data with the following elements:

  • A data and a time (UTC time)
  • A hash value computed using a has function (e.g. SHA 1 or SHA 256)
  • The identifier of the time-stamping unit (TSU) which produced the time-stamp token.

How does it work?

The client sends a timestamp request to the platform, which determines a signatory entity, takes a very precise reading of the date and time, signs and returns this information. The protocol used for these communications is commonly called TSP (“Time Stamping Protocol”) and is explained in the RFC 3161.

The signature of the responses is done using cryptographic equipment which must have an interface compliant with the PKCS#11 standard.
The administration of the service is carried out via a graphical interface, allowing authorized operators to manage the entities required to provide the TSP service.
Atos, a global leader in digital transformation and digital security, provides Metatime a timestamping solutions to generate securely timestamp tokens. The solution is sold as a service or as standalone product.

Metasign: a reliable signature creating and verifying secure transactions

In a context where organisations are moving to paperless transactions, it is necessary to electronically sign documents to guarantee their integrity and to be able to bring the proof of acceptance by the signer. The signature has to be verified strictly so as to detect any possible cause for invalidity.
