  • Patent number: 12250245
    Abstract: A cookie compliance management system enables automated evaluation of cookie compliance within an enterprise. The system determines whether a cookie set by an application in the environment is compliant with a policy. It comprises a workflow engine, a cookie discovery engine (CDE), a cookie characterization engine (CCE), a cookie policy engine (PE), and a cookie registry. The workflow engine receives a request to initiate an evaluation of an application for cookie compliance. The CDE is invoked and returns cookies that are set by the application. The CCE receives a set of base attributes associated with a cookie discovered by the CDE, and computes a set of descriptive attributes determined to be required to enable evaluation of the cookie according to a policy. The policy engine receives policy rules and the set of descriptive attributes and, in response, determines whether the cookie is compliant with the policy. The cookie registry stores cookie data.

  • Patent number: 12249002
    Abstract: A computer-implemented method that provides watermark-based image reconstruction to compensate for lossy encoding schemes. The method can generate a difference image describing the data loss associated with encoding an image using a lossy encoding scheme. The difference image can be encoded as a message and embedded in the encoded image using a watermark and later extracted from the encoded image. The difference image can be added to the encoded image to reconstruct the original image. As an example, an input image encoded using a lossy JPEG compression scheme can be embedded with the lost data and later reconstructed, using the embedded data, to a fidelity level that is identical or substantially similar to the original.

    Abstract: A novel structured random sample consensus protocol to greatly improve blockchain and distributed ledger technology throughput and scalability, while maintaining decentralization and high levels of security. The invention leverages small committees of fixed sizes, called “Clans,” threshold cryptography, and logical virtual districts, called “Tribes,” in order to deterministically random sample disparate nodes for sentiment analysis on a transactions validity, thereby only requiring a relatively small subset of nodes to validate any particular transaction or batch of transactions thus enabling much greater concurrency and parallel processing compared to other more linearized consensus algorithms, while maintaining high security.

  • Patent number: 12225138
    Abstract: This disclosure relates to field of cryptography and digital signatures. The constant theft of cryptocurrencies is due to compromise of the secret signing key inherently stored in a single location. Also, one of challenges in the existing ECDSA signature is single point failure, wherein the signing key (private key) is prone to theft. The disclosed technique overcomes the challenging in the existing techniques by party distributed signature that ensures the safety of the private key. The disclosed techniques slits the key in two parts and saves at two different locations/machines. Further based on a ECDSA based technique, the digital signature is obtained securely using several steps that includes generation of first two parts of digital signature at one party, generation of the second two parts of digital signature at second party, finally decrypting a complete digital signature at the first party.

  • Patent number: 12225003
    Abstract: Cross-channel user authentication is provided, to increase resilience of a computerized system to cyber-attacks and to fraudulent transactions. In a demonstrative scenario, a user utilizes his web browser on his laptop computer to log-in to a web server; which in turn extracts the IP address of the laptop computer. The web server triggers an application server to send a Push Notification to a Mobile App that had been installed on a smartphone of that user who just logged in; and that Push Notification causes that smartphone to respond to the application server with the IP address of the smartphone. If the IP address of the computer is not identical to the IP address of the smartphone, then the servers determine that the log-in attempt on the computer was possibly fraudulent, and fraud mitigation operations are initiated. Optionally, geo-location data, device orientation data, device motion data, or other parameters are used as part of the cross-channel authentication process.

  • Patent number: 12200129
    Abstract: A user device generates an initiate interaction request message comprising a state commitment. The user device provides the initiate interaction request message to a first server computer, which creates a verify state request message comprising an interaction index, an interaction index commitment, and a first commitment signature formed from the state commitment and the interaction index commitment. The user device receives the verify state request message, then generates a modified verify state request message comprising a user device public key, the state commitment, the interaction index commitment, and the first commitment signature. The user device provides the modified verify state request message to a second server computer. The second server computer verifies the state commitment, verifies the first commitment signature, and creates a second commitment signature formed from the state commitment and the interaction index commitment.

  • Patent number: 12192215
    Abstract: Embodiments described herein provide a design architecture for co-designing a controller and a watermarking signal for a cyber-physical system. During operation, the architecture can determine, in conjunction with each other, respective values of a first set of parameters indicating operations of the controller and a second set of parameters representing the watermarking signal. Here, the watermarking signal is combinable with a control signal from the controller for monitoring an output signal of the cyber-physical system for detecting malicious data at different time instances. Subsequently, the architecture can determine a state manager for determining the states of the cyber-physical system from the monitored output signal based on the first and second sets of parameters. The architecture can also determine a detector capable of identifying presence of an attack from the states of the cyber-physical system at a plurality of time instances using the watermarking signal.

  • Patent number: 12192185
    Abstract: A data transmission method includes a step in which a first device generates a first encrypted packet by encrypting a packet addressed to a second device with an associated first encryption key. A device to be a transmission destination of the first encrypted packet is determined. A second encrypted packet is generated by encrypting the first encrypted packet with an associated second encryption key, and the second encrypted packet is transmitted to the determined device. The method includes determining another device and executing the transmission step if the decrypted first encrypted packet is not addressed to the device itself in the determination regarding whether or not the decrypted first encrypted packet is addressed to the device itself and of further decrypting the first encrypted packet if the decrypted first encrypted packet is addressed to the device itself.

  • Patent number: RE50264
    Abstract: A system and method are provided for conditional delivery of electronic content such as images or video stream content over a communication network. In some embodiments, a condition for receiving such content is determined, for example a verification of a biometric fact as a face recognition or a finger print. The content will then be delivered conditioned on the satisfaction of the condition. In some embodiments, facial detection technology is used continually while sent content is being displayed to ensure that content is being viewed solely by the intended recipient. In some embodiments, the recipient's reaction to sent content is recorded on video and sent to the sender as a condition of viewing the sent content. In some embodiments, two or more users interact with one another in real time in a secure video conference.
