Abstract: When printing 3D objects designed by a particular designer, authentication information such as a serial number and a digital signature of the designer are inserted into a CAD file for printing the object. The authentication information is represented as physical structures in or on the 3D-printed object. The physical structures (e.g., pits, cavities of one or more shapes, etc.) can be detected by a scanner (e.g., an ultrasound or the like), and the detected authentication information can be transmitted to an authentication server that determines the authenticity of the 3D-printed object and transmits the authenticity determination to a user.

Abstract: A method and system secures an encryption key for utilization on a secured network by receiving, at a trusted node, an encryption key request from a requesting node, the encryption key request including a public encryption key of a public/private encryption key pair associated with the requesting node; determining, at the trusted node, if the requesting node has previously supplied enough virtual currency to support the request; choosing an encryption key for distributing to the requesting node when it is determined the requesting node has enough virtual currency; encrypting the chosen encryption key with the public encryption key of a public/private encryption key pair associated with the requesting node; and sending the encrypted encryption key to the requesting node.

Abstract: A method and system for embedding a database in a 3D object uses a 3D dimensional printing device and a computer-readable memory that stores a build sequence comprising instructions that, when executed by a processor, will cause the 3D printing device to form a three-dimensional object with an embedded data structure by depositing layers of build material and by including, in one or more of the layers, physical representations that represent a data structure.

Abstract: The present invention generally relates to systems and methods for document redaction. The disclosed techniques adapt to the needs of different levels of data sensitivity and different needs for disclosure or analysis by using pre-defined templates related to use cases, and mapping those to the relative sensitivity of private data types both in their natural form and after redaction by various redaction types. In this way, data is given the appropriate level of protection within the needs of a given use case.

Abstract: A system and method for enabling safety in and for initial impromptu meetings facilitated by electronic devices. Prior to the meeting, participants each download a same generated event ticket and the public key of the other meeting participant. At the meeting location, each individual's electronic device via a mobile application initiates close-proximity communication with the other mobile application; signs the ticket with its stored private key; exchanges signed tickets; verifies the received signed ticket using the downloaded public key; and compares the verified signed ticket with the downloaded ticket to authenticate the other individual.

Abstract: Methods and systems for categorizing users. A first set of communities and a second set of communities are identified based on a set of keywords and one or more messages posted by at least the users on one or more websites. The first set of communities corresponds to at least one of a product or a service, and second set of communities corresponds to at least one of a competitor-product or a competitor-service. The one or more conversations associated a user in at least one of the first set of communities or the second set of communities are determined. The one or more conversations correspond to exchange of messages at least between the user and a user-representative. The one or more conversations are analyzed to obtained one or more attributes. The users are categorized based on the one or more attributes.

Abstract: Methods and systems for providing secure recording of revisions made to electronic documents, using secure methods to validate the recorded changes, are disclosed. An electronic device making a change to an electronic document can transmit the change to the network. An audit log chain is residing on the network and shared among all the nodes on the network. A node on the network can verify a change of document made by other nodes and add a new block to the chain using one-way hashes, making the chain resistant to tampering. If an invalid block is detected, the system can send an auditing alert to the network. The audit log can be strongly resistant to tampering, providing reliable evidence for use in audit compliance, investigations, and business or court record keeping.
