  • Patent number: 11227062
    Abstract: Example implementations described herein are directed to systems and methods for selecting appropriate data samples and features in an access and privacy restricted system. Example implementations involve selection of appropriate samples (e.g. patients) which have enough data sources bringing highly important factors based on the experienced risk factors at other facilities, which is stored as metadata. The risk factor management puts more prioritization on some patients which have more data in the required data source than the other patients among all data sample candidates. The similarity of the training data sample can be a criteria to select new sample sets. Further, the risk factor management selects valuable features effectively based on metadata derived from other facilities. Example implementations help improve machine learning accuracy as part of daily system management in a facility, and can be deployed across facilities without compromising access or privacy restrictions of the data.

  • Patent number: 11227046
    Abstract: Disclosed herein is a method of performing a password challenge in an embedded system. The method includes receiving a password, scrambling the sub-words of the password pursuant to scramble control codes, retrieving a verification word, scrambling the sub-words of the verification word pursuant to the scramble control codes, and comparing the scrambled sub-words of the password to the scrambled sub-words of the verification word. Access to a secure resource is granted if the scrambled sub-words of the password match the scrambled sub-words of the verification word. The scramble control codes cause random reordering of the sub-words of the password and sub-words of the verification word in a same fashion, and insertion of random delays between the comparison of different sub-words of the password to corresponding sub-words of the verification word.

  • Patent number: 11222135
    Abstract: A method and system of protecting user sensitive information from an application program of a user device are provided. The application program to be installed is received on the user device. Permissions to resources of the user device for the application program are identified. For each permission, mapping the permission to one or more sections of a code of the application program. For each mapped section of the code, a recipient of user sensitive information facilitated by the permission is determined. For each recipient, it is determined whether the recipient should be restricted. Upon determining that the recipient should not be restricted, the user sensitive information facilitated by the permission is provided to the recipient. However, upon determining that the recipient should be restricted, alternate information to the recipient.

  • Patent number: 11212274
    Abstract: Techniques are disclosed for accelerating online certificate status protocol (OCSP) response distribution to relying parties using a content delivery network (CDN). A certificate authority generates updated OCSP responses for OCSP responses cached in the CDN that are about to expire. In addition, the certificate authority pre-generates cache keys in place of CDNs generating the keys. The certificate authority sends the OCSP responses and the cache keys in one transaction, and the CDN, in turn, consumes the new OCSP responses using the cache keys.

  • Patent number: 11133933
    Abstract: Techniques for rapid secure authentication and communications through multitenant components in a provider network are described. A main database cluster can request a burst cluster from a burst service, which can provide the main cluster with a shared secret associated with only a selected burst cluster. The main cluster can use the shared secret to encrypt a value that can be passed, via a proxy, to the selected burst cluster in a connection request. The selected burst cluster can validate that the connection request was truly originated by the main cluster by validating the encrypted value using the shared secret.

  • Patent number: 11121861
    Abstract: The generation of hash values become popular with the storage of pin code by an authentication server, since the authentication server knows only the result of the hash function and not the pin code itself. Each time an authentication is requested, a hash function is executed on the received pin code and then compared with the stored reference hash value of the initial pin code. In order to improve the security of the hash value, it is proposed a method to produce a secure hash value (R) from a plaintext (P), said method comprising: —producing a first result (H) using an hash function of the plaintext (P), —obtaining an initial floating value (U0) by converting the first result (H) into a floating number representation of the first value (H), —updating a floating value (Un) by executing at least once a Transcendental function (TF) on the initial floating value (Un?1), —obtaining the secure hash value (R) by mixing the first result (H) with the updated floating value (Un).

  • Patent number: 11068600
    Abstract: A system, method, and apparatus for secure router operation and initialization. A router may require at least two sets of credentials at different phases of initialization, thereby adhering to a multi-layered security approach. In a first phase of a router initializing for operation, a boot loader of the router may require a first authentication in order to unlock the full-disk encryption and commence booting into firmware. In a second phase, the firmware of the router may require second authentication to continue the initialization and to unlock the file-based encryption and access the settings of the router, after which the router may be fully operational.
