Abstract: A user requesting authentication is presented a keypad that includes multiple keys and respective keys include a character that is associated with a shape. Responsive to selection of a key, a first set of attributes is activated for selection. Responsive to determining a selection of an attribute from the first set of attributes, activating one or more additional sets of attributes associated with the first key. Responsive to determining a selection from the one or more additional sets of attributes, determining whether a selection of an additional key is made. Responsive to determining the selection of the additional key, activating for selection a first set of attributes and one or more additional sets of attributes of the additional key, and responsive to determining selections of keys and corresponding attributes associated with the selection of respective keys, determining the validity of the authentication code.

Abstract: Preserving privacy of deleted personal data is provided. A registration of a client device is received. The client device stores a plurality of personal data corresponding to a plurality of data subjects. A copy of a set of personal data corresponding to a particular data subject deleted from the client device is received along with metadata describing the set of personal data deleted from the client device and a hash key based on the set of personal data deleted from the client device. Access to the copy of the set of personal data deleted from the client device is granted in response to receiving an access request that includes the hash key corresponding to the set of personal data from the particular data subject within a defined period of time. The copy of the set of personal data is deleted after expiration of the defined period of time.

Abstract: A method, system and computer program product for providing user control of tracking user behavior. A request from a tracking implementer (e.g., website) for installing content (e.g., tracking cookies) on a user's computing device for tracking user behavior is detected. Alternatively, the installation of content by the tracking implementer on the user's computing device to track user behavior is detected. If the user had previously established a standard terms of service for the tracking implementer to abide in order to track the user's behavior, then a determination is made as to whether the tracking implementer agreed to accept such standard terms of service. If the tracking implementer did not agree to accept such standard terms of service, then the tracking implementer is blocked from tracking the user's online behavior, including blocking the tracking implementer from installing content on the user's computing device to track the user's behavior.
