According to one embodiment, a method, computer system, and computer program product for user authentication. The embodiment may include receiving, at an authentication server, respective multiple location coordinates from first and second registered devices. Storing, on the authentication server, respective moving windows comprising registered, device specific, last n location coordinates from the first and the second registered devices. Receiving a request to access the authentication server via the first registered device. The request comprises log-in credentials of a user and a first hash value calculated at the first registered device. Computing, at the authentication server, a second hash value using a set of the last n location coordinates from each of the respective moving windows. Comparing the first hash value and the second hash value. In response to the first and the second hash values being equal, and the log-in credentials being verified, granting access to the authentication server.

Location coordinate-based user authentication with device loss security tolerance

According to one embodiment, a method, computer system, and computer program product for user authentication. The embodiment may include receiving, from a first device, multiple location coordinates of the first device. The embodiment may include storing, on a second device, a second moving window comprising last n location coordinates of the multiple location coordinates. The embodiment may include receiving, from the first device, a request to access the second device, wherein the request comprises log-in credentials and a first hash value. The embodiment may include computing, on the second device, a second hash value based on the second moving window. The embodiment may include verifying the log-in credentials. The embodiment may include comparing the first hash value and the second hash value. In response to the first and the second hash values being equal, and the log-in credentials being verified, the embodiment may include granting access.

User authentication based on periodic sampling of location coordinates

A computer-implemented method for obfuscating sensitive information associated with mail delivery is disclosed. The computer-implemented method includes identifying that a piece of mail directed towards a potential recipient includes a particular type of sensitive information. The computer-implemented method further includes selecting a mail obfuscation policy for the particular type of sensitive information based on the particular type of sensitive information. The computer-implemented method further includes performing an obfuscation action with respect to the particular type of sensitive information based on the selected mail obfuscation policy.

Method for concealing sensitive mail return addresses

A method, computer system, and a computer program product for account security is provided. The present invention may include analyzing one or more financial accounts of a user and assigning a risk threshold to each of the one or more financial accounts. The present invention may include monitoring a vulnerability of each of the one or more financial accounts, wherein the vulnerability is monitored using a vulnerability score, the vulnerability score being generated based on user data. The present invention may include determining the risk threshold has been exceeded for at least one financial account based on a comparison of the vulnerability score and the risk threshold of the at least one financial account. The present invention may include preventing access to the at least one financial account in which the risk threshold has been exceeded.

Enhancing investment account security

A system and method for assigning assessment tasks includes determining tasks in need of completion, where the tasks include assessing a set of documents containing medical patient data and providing a judgment (e.g., classification or label) based on the contents of the document. A process also includes selecting one or more reviewers based on the one or more tasks and providing one or more documents from the set of documents to each of the selected one or more reviewers for completion of the one or more tasks. The process further includes receiving a result of the one or more tasks after completion by the selected one or more reviewers and storing the result in an electronic medical record database.

System for assignment of assessment tasks based on task criteria and reviewer credentials

A system and associated method for assessing level of completeness of healthcare data storage based on collected data. The system includes a collection system, a measurement system, an expectation system, and an alerting system. In a method of assessing the health of stored data, the system collects real-time data from at least one data source, determines measurements for a plurality of parameters based on the collected data, and generates expectations for a future period of time for the plurality of parameters based on data analysis technique. The system also compares the expectations for the future period of time to subsequent measurements collected for that period of time to determine whether the subsequent measurements satisfy an expectation threshold and provide an alert to a client terminal. The alert is a result of the comparison of the expectations and the subsequent measurements and provides an assessment of data storage quality and alerts on anticipated deficiencies.
