  • Patent number: 11669629
    Abstract: Aspects of the disclosure provide a technological improvement to a cipher by improving data security of format-preserving encryption (FPE), by, inter alia, embedding specific key identifiers for rotating keys directly into ciphertext. Aspects of the disclosure relate to methods, computer-readable media, and apparatuses for improving data security in a format-preserving encryption (FPE) context by using specific methods of rotating and identifying the appropriate encryption key from among numerous rotating keys stored in a key data store. Specific to FPE, a plaintext of the data and its corresponding ciphertext of the data remain the same in length/size; yet the methods, computer-readable media, and/or apparatuses disclosed herein permit embedding of an identification of a specific key among the plurality of rotating keys for the particular ciphertext without compromising the technical requirements of FPE.

  • Patent number: 11057357
    Abstract: The disclosure includes novel encryption and/or decryption methods and systems that provide various security benefits. More specifically, the disclosure includes a description of a file encryption process and its ability to dynamically control permissions on who is allowed to decrypt the file. Moreover, the disclosed process permits an encrypted file to be freely distributed without losing the ability to govern/regulate decryption.

  • Patent number: 10135796
    Abstract: An apparatus with one or more masking rules stored in a memory receives unmasked data associated with a first session identifier via a network and converts the received unmasked data into masked data by applying the one or more masking rules to the unmasked data. The apparatus generates a first mapped identifier associated with the unmasked data and first session identifier. The apparatus also receives, via a network, a second mapped identifier associated with a second session identifier. Upon receiving the second mapped identifier and second session identifier, the apparatus determines whether the second session identifier corresponds to the first session identifier and finds the first mapped identifier corresponding to the received second mapped identifier. The apparatus retrieves and sends the unmasked data associated with the first mapped identifier.

  • Patent number: 10084722
    Abstract: A computer system deploys monitoring agents that monitor the status and health of the computing resources. An analysis engine aggregates and analyzes event information from monitoring agents in order to support self-configuration, self-healing, self-optimization, and self-protection for managing the computer resources. If the analysis engine determines that a computing resource for a software application is approaching a critical status, the analysis engine may issue a command to that computing resource in accordance with a selected policy based on a detected event pattern. The command may indicate how the computing resource should change its behavior in order to minimize downtime for the software application as supported by that computing resource. The computer system may also support a distributed approach with a plurality of servers interacting with a central engine to manage the computer resources located at the servers.

  • Patent number: 9602284
    Abstract: A user workstation stores a vendor identifier and encrypted data comprising a first string of randomized data, a second string of randomized data, and encrypted text, the encrypted text further comprising a first security answer. The user workstation receives credentials information and a second security answer. The user workstation then generates an encryption key. Further, the user workstation uses the encryption key to decrypt the encrypted text and extract the first security answer. Then, the user workstation compares the second security answer with the first security answer and authenticates the second username if the second security answer is the same as the first security answer.
