According to an aspect, a method for accessing a computing device includes receiving, by the computing device, an authentication credential for recovery access to the computing device, the authentication credential being different from an authentication credential used to access encrypted data on the computing device, obtaining, in response to receipt of the authentication credential for recovery access, a first key portion stored on the computing device, transmitting, over a network, a request to receive a second key portion, receiving, over the network, a response that includes the second key portion, recovering a decryption key using the first key portion and the second key portion, and decrypting the encrypted data on the computing device using the decryption key.

In an example implementation according to aspects of the present disclosure, a system receives behavioral biometric data associated with a user of a computing device. The system determines whether an identity of the user is authenticated based on a comparison of the received behavior biometric data and historical behavioral biometric data associated with the user of the computing device. In response to determining that the identity of the user is not authenticated based on the comparison of the received behavioral biometric data and the historical behavioral biometric data, the system receives physiological biometric data associated with the user. The system determines whether the identity of the user is authenticated based on a comparison of the received physiological biometric data and historical physiological biometric data associated with the user of the computing device.

Human interaction with a webpage may be determined by processing an event stream generated by the client device during the webpage interaction. A classification server receives the event stream and compares components of the event stream, including components of an event header message, with prerecorded datasets. The datasets include prerecorded event streams having a known interaction type. Training clients may be provided for generating the prerecorded datasets.

A method and system for initiating message listening and routing message content to authorized user devices is disclosed. For a second user device to receive notifications regarding records of a first user, the second user device provides information identifying the first user to a notification service. The notification service verifies the identifying information. The notification service initiates one or more listeners to listen for messages flowing over a messaging bus that are relating to the first user. Once a message is identified, at least a portion of the message is used to generate a notification that may be sent to the second user device.

The present system relates a platform for addressing the optimal privacy-accuracy trade-off in the revelation of a user's valuable information to a third party. Specifically, the present system formalizes the privacy-accuracy trade-off in a precise mathematical framework, wherein mathematical formalization captures user's privacy preference with a single parameter. The system possesses a revelation method of user data that is optimal, in the sense of abiding by user's privacy preference while providing the most accurate description to third party subject to the aforementioned privacy preference constraint.

Methods and systems for detecting undesirable computer files based on scanning and analysis of information contained within an associated digital certificate chain are provided. According to one embodiment, a file having associated therewith a certificate chain is received. A type and structure of the file are identified. A location of the certificate chain is determined based on the identified type and structure. A signature of the file is formed by extracting a targeted subset of information from the certificate chain. The file is evaluated by comparing the signature with a set signatures having a known desirable or undesirable status. The file is classified based on a result of the evaluating into a category of multiple categories, including one indicative of an associated file being an undesired file or a file suspected of being undesired. The file is handled in accordance with a policy associated with the category.

A computer system that interfaces with a blockchain is provided. The computer system receives match data for a match between a first data transaction request that is associated with a first identifier and a second data transaction request that is associated with a second identifier. A first blockchain transaction is generated based on the match data and stored to a blockchain. At least one further blockchain transaction is generates that splits the match into two different transactions—one between the first identifier and an intermediary and the second between the intermediary. These are recorded to the blockchain via the further blockchain transactions.

A system and method for processing a multiple data controller workflow fully honors data subject opt-outs but nevertheless takes advantage of the synergy of the combined data from multiple controllers to improve the effectiveness of messaging. A data services provider performs data resolution processing against the data from each data controller. Using the results of the resolution processing, opt-out lists that are in different formats and that may track different sorts of data may all be used for the joint campaign. Metadata is added to the data so that the source data controller is tracked through the processing. The data is then combined, resulting in a master opt-out list. If a data subject has opted out with respect to any controller, then the opt-out is applied to the joint campaign.

Techniques are disclosed relating to credential managers. In some embodiments, a computing device maintains a credential manager that stores, in a protected manner, a set of credentials for authenticating a user and metadata about the credentials. The computing device stores an instance of the metadata externally to the credential manager. The computing device uses the externally stored metadata to determine whether the set of credentials includes a particular credential associated with a service and, in response to determining that the set of credentials includes the particular credential, displays an indication of the particular credential. In some embodiments, the computing device receives a selection of the displayed indication by the user and, in response to the selection, sends a request for the particular credential to the credential manager.

A method includes receiving, by a universal authentication application from a resource provider computer, a user credential verification request message comprising a user identifier, server computer data, and interaction data for an interaction. The universal authentication application transmits the user credential verification request message to a browser that invokes the authenticator to verify biometric information of a user. The universal authentication application receives a user credential verification response message from the authenticator. The user credential verification response message includes signed interaction data. The universal authentication application sends the user credential verification response message to the resource provider computer. The resource provider computer provides at least the signed interaction data to a plurality of server computers to retrieve a plurality of portable device credentials respectively associated with the plurality of server computers.
