Latest Patents

One of Urita's latest patents is a "Network system for transporting security-protected data." This system integrates security protection facilities and involves a transmission unit and a reception unit connected via a network. The transmission unit features a data management unit that centrally manages source data stored across multiple distributed storage units. Upon receiving a data transmission request from a local terminal, a data collection unit gathers the requested data items. A security processor then applies appropriate security measures based on the data's confidentiality level. An identification data attaching unit adds identification data to the transmission data, informing the recipient of the security processes applied. The transmitter subsequently sends the security-protected data over the network. In the reception unit, a receiver accepts the data, and an identification data extracting unit retrieves the attached identification data. This allows an unprotection unit to reconstruct the original data contents.

Another notable patent is the "Method of and apparatus for retaining and verifying data on recording." This invention ensures the validity of data recorded on mediums such as rewritable magneto-optic disks. When registering multiple documents on the same medium, an n-th authenticator is generated by encrypting the n-th document's data. This authenticator is recorded alongside the document data. When registering the (n+1)-th document, a new authenticator is created by encrypting the previous authenticator with the new document data.
