Abstract: The present disclosure provides a secure, user-transparent, and highly efficient content provider-specific identifier (“CPSID”), sometimes referred to as a “read-only cookie” (“ROC”). These content provider-specific identifiers may be generated by the client device and encrypted with a public key of the content provider, preventing third parties from indirectly identifying matches, and obviating the need for provider-side cookie matching tables and resource-intensive tracking communications. The generation of content provider-specific identifiers may be controlled by user policies, such that identifiers are only created for content providers with compliant terms of service (ToS), e.g. retrievable from a predetermined address within the domain; content providers that are on a whitelist (e.g. for which the user has explicitly provided consent); and/or content providers that are not on a blacklist (e.g. for which the user has explicitly refused consent).

Abstract: Various embodiments relate to a method for masked decoding of a polynomial a using an arithmetic sharing a to perform a cryptographic operation in a data processing system using a modulus q, the method for use in a processor of the data processing system, including: subtracting an offset ? from each coefficient of the polynomial a; applying an arithmetic to Boolean (A2B) function on the arithmetic shares of each coefficient ai of the polynomial a to produce Boolean shares âi that encode the same secret value ai; and performing in parallel for all coefficients a shared binary search to determine which of coefficients ai are greater than a threshold t to produce a Boolean sharing value {circumflex over (b)} of the bitstring b where each bit of b decodes a coefficient of the polynomial a.

Abstract: Techniques and mechanisms for using passively collected network data to automatically generate a fingerprint prevalence database without the need for endpoint ground truth. The process first clusters all observations with the same fingerprint string and similar source and destination context. The process then annotates each cluster with descriptive information and uses a rule-based system to derive an informative name from that descriptive information, e.g., “winnt amp client” or “cross-platform browser”. Optionally, the learned database may be augmented by a user to clarify custom process labels. Additionally, the generated database may be used to report the inferred processes in the same way as databases generated with endpoint ground truth.

Abstract: The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that, among other things, authorize initiated exchanges of data in real-time based on dynamically generated tokenized data. For example, an apparatus may receive first positional data identifying a first geographic position of a client device and based on the first positional data, the apparatus may determine a value of a parameter characterizing an exchange of data between the client device and a terminal device disposed proximate to the client device during a temporal interval. The apparatus may transmit data requesting a pre-authorization of the data exchange to a computing system, which perform operations that pre-authorize the data exchange in accordance with the parameter value and transmit a digital token representative of the pre-authorized data exchange to the terminal device. The digital token may be valid during the temporal interval and may include a cryptogram associated with the client device.

Abstract: An active attestation apparatus verifies at runtime the integrity of untrusted machine code of an embedded system residing in a memory device while it is being run/used with while slowing the processing time less than other methods. The apparatus uses an integrated circuit chip containing a microcontroller and a reprogrammable logic device, such as a field programmable gate array (FPGA), to implement software attestation at runtime and in less time than is typically possible with comparable attestation approaches, while not requiring any halt of the processor in the microcontroller. The reprogrammable logic device includes functionality to load an encrypted version of its configuration and operating code, perform a checksum computation, and communicate with a verifier. The checksum algorithm is preferably time optimized to execute computations in the reprogrammable logic device in the minimum possible time.
