Timestamping your digital file with Veridocx provides evidence, subject to the rules of admissibility in your jurisdiction, that the file existed in that exact state at that point in time.

Traditional methods of doing this, such as mailing documents to yourself to obtain a post mark or emailing files to yourself to obtain an email timestamp, are not tamper proof. Contents of an envelope can be tampered with after receipt of the postmark and the time and other details in email headers can be modified easily.

A Veridocx Timestamp, in contrast, is reliable and non-repudiable.

Very.

Veridocx uses timestamping equipment supplied by Thales, which is audited every 12 hours by the National Institute of Standards and Technology (NIST) in the United States^†. At any point in time, Veridocx Timestamps can always be traced back to NIST to verify their accuracy.

NIST is an agency of the US Department of Commerce and a national source of reliable time for the US government. NIST is completely independent of Veridocx and Veridocx has no ability to influence the time provided by NIST or the audit process^†.

Veridocx's timestamps are generated by a tamper proof Hardware Security Module which ensures that no one can compromise the timestamping process. Any attempts to tamper with a Timestamp Server will invalidate the audit and the Server will not issue timestamps until the next audit is completed successfully.

Our Timestamp Servers are compliant with ETSI TS 101 861, ETSI TS 102 023 and PKIX (RFC 3161), and have been validated to FIPS 140-2 Level 3 and Common Criteria EAL4+.

Our Timestamp Servers generate standard PKCS#7 timestamps, as described by IETF RFC 3161. The timestamp contains the time and date our timestamp infrastructure saw the hash of your file, the hash itself, and a Time Attribute Certificate auditing the accuracy of the Timestamp Server. All this information is digitally signed.

^†In the event that NIST audits are not available, Veridocx may obtain audits from other sources.

Timestamps can be verified by using the Verify section of our website. Even if our service is not available, a timestamp can be verified independently by a suitably competent person.

By using the Verify section of our website you can easily upload a file to see the date and time that exact file was timestamped.

Alternatively, our timestamp infrastructure generates standard PKCS#7 timestamps, as described by IETF RFC 3161. The timestamp contains the time and date our timestamp infrastructure saw the hash of your file, the hash itself, and a Time Attribute Certificate auditing the accuracy of the Timestamp Server. All this information is digitally signed.

A competent person familiar with PKCX#7 timestamp certificates can verify that the timestamp is valid, and also verify that the hash within it matches the hash of your file.

You can timestamp and store files of up to 150 megabytes with us.

Any digital file that you can upload. That includes PDFs, Microsoft Office files, photos, videos, MP3s, etc. Pretty much anything you can store on your computer.

The digital fingerprint generated by our timestamp certification process is unique to each individual file. It is a statistically infeasible that two different files will ever generate the same digital fingerprint.

If a single bit is changed in the file, the digital fingerprint will change and the file’s link to its Veridocx timestamp certificate will be broken.

Opening and saving (rather than simply closing) a Microsoft office document without making any amendments to the content could potentially amend data fields in the file which would constitute a change in the file.

Likewise, opening and resaving an Adobe PDF document in Adobe Acrobat or resaving a jpeg file may cause a change in the file that will generate a different digital fingerprint.

By continuing to store your file with Veridocx, we can guarantee that an original copy of your certified file is maintained by us. Should you not wish to continue to store your file with us, you should take particular care in storing your original file and ensure no modifications occur to it.

All of our timestamps are use UTC (Coordinated Universal Time), the world's primary time standard. UTC is used because it does not depend on timezones - a given time and date in UTC is the same across the world.

Please log into your account select a file to choose your sharing options.

If you have the file stored with us, you can retrieve it in the accounts section.

If you don’t have a stored copy with us, please visit "Why should I continue to store my file with Veridocx?" below.

Storing your certified file with us means that:

• you are guaranteed that the stored file will be the original file which has been timestamped, safe from loss or modification.
• you can securely share a copy of the file with your friends and associates through our service.

Once issued, your Veridocx timestamp is valid in perpetuity regardless of whether Veridocx is around or not.

As long as you have a copy of your original file and a digital copy of the Veridocx Timestamp Certificate, a suitably competent person can independently verify the authenticity of your timestamp.

Our timestamp infrastructure generates standard PKCS#7 timestamps, as described by IETF RFC 3161. The timestamp contains the time and date our timestamp infrastructure saw the hash (or fingerprint) of your file, the hash itself, and a Time Attribute Certificate auditing the accuracy of the Timestamp Server. All this information is digitally signed.

A competent person familiar with PKCX#7 timestamp certificates can verify that the timestamp is valid, and also verify that the hash within it matches the hash of your file.
