    摘要: An on-ledger certificate authority operates a node of a distributed ledger that controls a certificate issuance store and a certificate revocation store. When the certificate authority issues a certificate, the node issues a ledger transaction with an instruction to store a validation hash of the certificate in the issuance store, and when a certificate is revoked, a ledger transaction with an instruction to store the serial number of the certificate in the revocation store. As such transactions propagate throughout the ledger, the instructions are executed by on-ledger verifiers in their local replicas of the stores. An on-ledger verifier validates a certificate by verifying that its serial number is not in the revocation store while its validation hash is in the verifier's replica of the issuance store.

    摘要: A method and system are provided for multifactor identification of a subject over a network using a rich credential, with selective disclosure of attributes and selective presentation of verification factors. A credential presentation application negotiates with a verifying server to agree on attributes to be disclosed and verification factors to be presented, and removes unneeded attributes and verification data from the rich credential by pruning subtrees from a typed hash tree without invalidating a signature that covers the root label of the tree. The credential presentation application proves knowledge of a private key, and as agreed upon may prove knowledge of a password and may arrange for biometric presentation applications to present one or more biometric samples to the verifier, which performs presentation attack detection and verifies the samples against verification data in the rich credential.

    摘要: A method of facilitating the browsing of a plurality of result sets by a user. The method includes displaying a plurality of queries on a computer display, each query having a corresponding result set, the plurality of queries thereby constituting a set of displayed queries, and displaying the result set of a selected displayed query in response to the user selecting the query from the set of displayed queries via a user interface procedure, while continuing to display the set of displayed queries so the user can subsequently select other queries from the set of displayed queries to thereby interleave browsing the result sets of the queries in the set of displayed queries.

    摘要: A method of activating credentials that are stored encrypted while inactive. In one embodiment a decryption key is retrieved from a key storage service after the device authenticates to the service by sending a passcode and/or a biometric key, a public key and a signature computed with a private key, the service verifying the signature and comparing a hash of the public key and the passcode and/or biometric key to a reference hash.

    摘要: A method for visiting a results page of a time-varying result set of a search query. The method includes displaying to a user a list of results belonging to the visited page, each result comprising a hyperlink to a document, a result being de-emphasized if the URL used in its hyperlink is present in a set of URLs of results that are deemed to have been seen by the user. When the user clicks or taps a page menu button to navigate to a different page, the method further includes adding to that set the URLs of the results of the visited page. Page menu buttons are highlighted if they pertain to pages containing results deemed to have been seen by the user.

    摘要: A method of controlling access to an interaction context of a multi-user application includes receiving and tracking over time login requests pertaining to one of a plurality of user accounts of a virtual application instance of the multi-user application, each login request including a login password and each user account including a user password. A login request for the user account is rejected when the login password fails to match the user password of the user account. Access to the user account is denied when a consecutive number of times a login request for the user account is rejected reaches a selected limit. The user is prompted to change the user password of the user account and given limited access to the user account to do so when the user password is a permanent password and a cumulative number of rejected login requests for the user account reaches a selected threshold.

    摘要: A public key infrastructure (PKI) includes a subject, a verifier, and certificate authority that issues a first unsigned certificate to the subject that binds a public key of the subject to long-term identification information related to the subject and maintains a certificate database of unsigned certificates in which it stores the first unsigned certificate. The verifier maintains a hash table containing cryptographic hashes of valid unsigned certificates corresponding to the unsigned certificates stored in the certificate database and including a cryptographic hash of the first unsigned certificate. The subject presents the issued first unsigned certificate to the verifier for authentication and demonstrates that the subject has knowledge of a private key corresponding to the public key in the unsigned certificate.

    摘要: A PKI includes an off-line registration authority that issues a first unsigned certificate to a subject that binds a public key of the subject to long-term identification information related to the subject and maintains a certificate database of unsigned certificates in which it stores the first unsigned certificate An on-line credentials server issues a short-term disposable certificate to the subject that binds the public key of the subject from the first unsigned certificate to the long-term identification information related to the subject from the first unsigned certificate. The credentials server maintains a table that contains entries corresponding to valid unsigned certificates stored in the certificate database. The subject presents the short-term disposable certificate to a verifier for authentication and demonstrates that the subject has knowledge of a private key corresponding to the public key in the short-term disposable certificate.
