Patent number: 11669465Abstract: This disclosure is directed to a computing system that performs techniques relating to the secure storage, maintenance, and retrieval of data. Techniques described in this disclosure may prevent, limit, or otherwise insulate the data from unauthorized access by hackers, rogue devices, and unauthorized users. In some examples, a computing system may store a file by fracturing the file into multiple data blocks, encrypting the data blocks or the data stored within the data blocks, and storing the data blocks in scattered locations on a network. Further, the computing system may occasionally move at least some of the stored data blocks, and may, upon moving such data blocks, reencrypt the moved data blocks with a different encryption key. Still further, the computing system may inject fake data and/or fake data blocks into the system.Type: GrantFiled: January 7, 2021Date of Patent: June 6, 2023Assignee: Wells Fargo Bank, N.A.Inventors: Basil F. Nimry, Nicholas Gillis, Ankush Bhatia

Patent number: 11647010Abstract: The technology disclosed relates to non-intrusively enforcing security during federated single sign-on (SSO) authentication without modifying a trust relationship between a service provider (SP) and an identity provider (IDP). In particular, it relates to an assertion proxy receiving a verified assertion from an IDP obtained from an assertion that is generated when a user logs into a service provider (SP) and is verified in dependence upon the IDP's public key. It also relates to evaluating the verified assertion against one or more security policies. It further relates to forwarding the verified assertion evaluated to the SP and causing establishment of a single sign-on (SSO) authenticated session without modifying the assertion.Type: GrantFiled: July 2, 2021Date of Patent: May 9, 2023Assignee: Netskope, Inc.Inventors: Lebin Cheng, Krishna Narayanaswamy, Kartik Kumar Chatnalli Deshpande Sridhar

Patent number: 11645399Abstract: Disclosed are various embodiments for searching encrypted data. A search query containing a plaintext key can be received from a client device or other application. A request can then be sent to a storage engine for a ciphertext key of a node of a binary tree, the node representing an encrypted key-value pair that includes the ciphertext key. The ciphertext key can be decrypted using a cryptographic key to generate a decrypted ciphertext key. Then, the decrypted ciphertext key can be compared to the plaintext key. A determination can then be made as to whether the encrypted key-value pair represented by the node of the binary tree satisfies the search query based at least in part on a comparison of the decrypted ciphertext key to the plaintext key.Type: GrantFiled: January 11, 2021Date of Patent: May 9, 2023Assignee: American Express Travel Related Services Company, INC.Inventor: John Orlando Keleshian Moxley

Patent number: 11627161Abstract: A data diode provides a flexible device for collecting data from a data source and transmitting the data to a data destination using one-way data transmission across a main channel. On-board processing elements allow the data diode to identify automatically the type of connectivity provided to the data diode and configure the data diode to handle the identified type of connectivity. Either or both of the inbound and outbound side of the data diode may comprise one or both of wired and wireless communication interfaces. A secure reverse channel, separate from the main channel, allows carefully predetermined communications from the data destination to the data source.Type: GrantFiled: August 2, 2021Date of Patent: April 11, 2023Assignee: Fend IncorporatedInventors: Sang Cheon Lee, Colin Patrick Dunn, Paul Carroll, Philip Quebe

Patent number: 11620392Abstract: A database-management system provides sargable evaluation for query predicates that compare an “LHS” encrypted database-column operand to an “RHS” expression operand. The system directly compares the two operands if all their attributes match. If the operands are encrypted string-type values differing only in length, the system truncates the RHS or pads it with encrypted blanks and, if a truncation loses meaningful data, evaluates the predicate as never satisfying an equality condition. In all other cases, if all attributes of a plaintext RHS don't match those of the plaintext data encoded into the LHS column, the system attempts to cast the RHS to match the plaintext LHS data. An error condition or data loss at this step allows the system to sargably evaluate the predicate without further analysis, but if the casting is successful and error-free, the system encrypts the resulting RHS and performs a sargable predicate evaluation.Type: GrantFiled: February 9, 2021Date of Patent: April 4, 2023Assignee: International Business Machines CorporationInventors: Xiaohong Fu, James W. Pickel, Yao Ching Stephen Chen, Jeffrey W. Josten, Nina Bronnikova, Sarbinder S. Kallar, Shengxi Suo
