  • Patent number: 11151271
    Abstract: A system with an interactive user interface for a plurality of users to author an electronic document simultaneously is described. The system displays visual feedback on the interface to prevent the users from interfering with one another. The system displays data from a remote database linked into the document based on unique identifiers. The data is displayed as an “artifact.” The system monitors and tracks each user's access category level, as well as the access category level of each piece of data pulled from the remote database. The system compares a user's category level to the data from the database to make visible only the portions of the document the user has the appropriate access category level to view and/or modify. The portions of the document that have a higher category level than the user will be hidden from the user either in part or completely. Also, there may be an indicator to the user of such redacted or hidden content from the user's viewer.

  • Patent number: 10929392
    Abstract: Generally described, one or more aspects of the present application correspond to machine learning techniques for generating realistic question-answer (QA) pairs for populating an initial community ask feature of electronic store item detail pages. The machine learning model can use a shared encoder to generate an embedding of a seed sentence from existing description of an item, and then pass that embedding to a question decoder to generate a question. The embedding of the seed sentence can be combined with a state representation of the question and provided to an answer decoder, which can generate an answer to the generated question. This can help overcome the cold start problem, where customers are less likely to ask questions about items that have no existing QA set. This can also help surface relevant information about items in a concise QA format that is easy for customers to find and read.

  • Patent number: 10911221
    Abstract: A first hash value is calculated by using a first input value that is stored in a first set of registers. The first hash value is then stored in a second set of registers. A second input value is stored in the first set of registers after calculating the first hash value. The second hash value is calculated based on the first hash value and the second input value. During the calculating of the second hash value, the first hash value is shifted from the second set of registers to a portion of the first set of registers when the calculating of the second hash value has reached a state where the portion of the first set of registers is no longer used to store the second input value.

  • Patent number: 10826912
    Abstract: Techniques for computer security, and more specifically timestamp-abased authentication, are described. Some implementations provide an authentication method that utilizes an authentication process that is shared as a secret between a first and second computing system. The process provides as output a number that is based on a timestamp. The first computing system executes the authentication process using a timestamp obtained from its clock. The resulting number is transmitted to the second computing system, possibly along with other authentication data, such as a username and/or password. In response, the second computing system executes the authentication process using a timestamp obtained from its clock. If the numbers generated by the first and second computing systems match, the first computing system is authenticated.

  • Patent number: 10805084
    Abstract: Disclosed are examples of decentralized systems and related apparatus, devices, computer program products, and methods for secure access of digital content. In some implementations, a first request from a client to access encrypted digital content includes a call on a digital contract. The call passes an ephemeral key set encrypted with a public key of a consumer. A transaction identifying the first request in association with the encrypted ephemeral key set is recorded in the digital contract. The transaction is identified by a transaction identifier (ID), which is sent to the client. A second request from the client includes: an authorization token including the transaction ID, and a signature of the consumer. Authorization of the consumer is verified based on the authorization token. A transaction identifying one or more keys is recorded in the digital contract. The digital content can be re-encrypted and sent to the client.
