Abstract: Methods and systems for securing a data connection for communicating between two end-points are described herein. One of the end-points may be a server and the other of the end-points may be a client that wants to communicate with the server. The data connection may be secured based on a previously-established secure connection and/or a self-signed or self-issued certificate. In some variations, by using the previously-established secure connection and/or a self-signed or self-issued certificate, the secure communication between the server and the client may be conducted without using a third-party authentication service and without requiring a third-party CA to issue a certificate for the server.

Abstract: A novel method for managing firewall configuration of a software defined data center is provided. Such a firewall configuration is divided into multiple sections that each contains a set of firewall rules. Each tenant of the software defined data center has a corresponding set of sections in the firewall configuration. The method allows each tenant to independently access and update/manage its own corresponding set of sections. Multiple tenants or users are allowed to make changes to the firewall configuration simultaneously.

Abstract: A communication device includes: a counter, a pseudo-random number generator, a symbol generator, a modulator, and a controller. The counter counts symbols transmitted to a correspondent device. The pseudo-random number generator generates a pseudo-random number corresponding to a count value of the counter. The symbol generator generates a transmission symbol from a transmission signal and the pseudo-random number. The modulator generates a modulated signal from the transmission symbol. When a disruption of a communication with the correspondent device is detected, the controller selects, from among a plurality of restoring times determined in advance, a restoring time for resuming the communication, and gives the counter a count value assigned in advance to the selected restoring time. The counter resumes a counting operation from the count value given from the controller when the communication device resumes a communication with the correspondent device.

Abstract: A system for applying fingerprinting/watermarking of consumer data, and analyzing “wild files” of consumer data to assign a guilt score for a particular party who may have leaked the data, allows the owner of data sources (“Data Owners”) to identify and assert ownership of textual data that has been distributed outside of their firewall in the clear (i.e., without encryption), either intentionally or unintentionally, and assign guilt to parties misusing the data. The system can be used by Data Owners who transmit, lease, or sell data to individuals or organizations (“Trusted Third Parties” or “TTPs”) to recognize and assert ownership of their data in the case where one or more TTPs leaks the data (the leaked file is defined as a “Leaked Subset”) into the hands of others (“Bad Actors”) who either knowingly or unknowingly use the data illegally.

Abstract: An apparatus includes a tester to detect a biological signature of a biological sample, a processor, and a memory operably coupled to the processor. The memory stores instructions to cause the processor to receive an indication of the biological signature from the tester, and to generate, using a smart contract and through communication with a distributed ledger, a cryptographic token including a digital identifier based on the biological signature.

The tester can detect the biological signature within a predetermined test duration that is less than a DNA sequencing duration associated with the biological sample, and the biological signature has a data precision sufficient to uniquely identify the biological sample from a plurality of biological samples.
