Latest Patents

One of Ruubel's latest patents is titled "System and method for field-verifiable record authentication." This invention involves adding a code as a marking to a document, which encodes an identifier that maps to a copy of the document stored in a database. The database copies of stored documents are preferably digitally signed. Users can extract the document identifier from the marking on a purported authentic version of the document using a device such as a smartphone. They can then retrieve a copy of the document from the corresponding location in the database and visually compare it with the purported authentic version.

Another significant patent is "Non-deterministic time systems and methods." This invention utilizes a capture device, such as a camera or sound recorder, to record an event that includes a visual and/or audible presentation of a non-deterministic time value. This time value is generated as a function of a calendar value created at time intervals, serving as a root hash value of a distributed, hash-tree document authentication infrastructure. If the non-deterministic time value included in the recording does not match the corresponding calendar value, the recording may be assumed to be altered. Digital time-stamping may also be included to reduce the opportunity for back-dating of the recording.
