Abstract: Improved watermarking techniques for text content are disclosed. An example methodology implementing the techniques includes selecting a sequence of text characters to form a watermark and representing at least one text character of the sequence of text characters by a code which, when inserted into text content, does not affect the appearance of the text content. The methodology also includes embedding the code which represents the at least one text character of the watermark into text content so that the code enables identification of the at least one text character upon extraction of the code from the text content.

Abstract: In accordance with one disclosed method, a first computing system may receive a message from an application hosted on a second computing system, the message being indicative of an event of the application. In response to receiving the message, the first computing system may generate a notification indicative of the event and send the generated notification to a client device. The first computing system may receive a response to the notification from the client device, and may process the response so as to cause the application to take an action responsive to the event.

Abstract: Systems and methods for Optical Character Recognition (“OCR”) based anti-spoofing for Unicode homograph. The method comprises: performing operations by a computing device to make an OCR identification on an original electronic address so as to obtain an OCR electronic address; encoding (a) the original electronic address to obtain an encoded access address and (b) the OCR electronic address to obtain an encoded OCR electronic address; comparing the encoded access address to the encoded OCR electronic address; and determining if a Unicode homograph spoofing situation exists based on results of the comparing.

Abstract: Systems and methods for controlling access to a mobile device. A method for unlocking a mobile device includes detecting a user input comprising two or more user actions performed at one or more physical input buttons of the mobile device when the mobile device is in a lock state. The lock state prevents use of at least one functionality of the mobile device. Each user action corresponds to a code. The method also includes determining whether the detected user input is valid, and changing a state of the mobile device from the lock state to an unlock state to enable the use of the at least one functionality of the mobile device if the detected user input is valid.

Abstract: A computer system is provided. The computer system includes a memory and at least one processor coupled to the memory and configured to recognize a user input field of a web site displayable in a browser, the website identified as a security risk based on a whitelist of website addresses; determine that a sequence of characters within the user input field matches one or more entries in a list of partial passwords in response to the web site being identified as a security risk; and prevent the user from entering additional characters into the user input field in response to the determination, to block receipt of the password by the web site. The determination may be performed in response to a count of characters in the sequence of characters exceeding a threshold.

Abstract: Methods and systems are described for prioritizing notifications based on user responses. The system may include determining a first score indicative of a first relevance of a notification to a first user at a first client device. The first score is determined based on at least metadata characterizing the notification. The notification is prioritized for the first user based on at least the first score. The notification is presented at the first client device based on at least the prioritization for the first user. A second score is determined that is indicative of a second relevance of the notification to a second user at a second client device. The second score is determined based on at least a response to the notification from the first client device.

Abstract: Methods, systems, and computer-readable media for adjustment of display of applications on an endpoint device are presented. A computing device may receive coordinates for an endpoint device. The coordinates may be representative of dimensions of a canvas on which to render an image for display on a screen of the endpoint device. Subsequently, the computing device may provide an image of a remote application to the endpoint device. Then, the computing device may provide information to the endpoint device in response to receipt of input by the endpoint device. The input by the endpoint device may be an input received on the image of the remote application and may be indicative of an editable area of the canvas. The information provided by the computing device may enable adjustment of a size or location of an input area of the canvas.

Abstract: Described embodiments provide systems and methods for providing remote application action feed cards. A ticket can be received from a client device. The ticket can be indicative of an action of a remote application and the remote application can be accessible by a group of users. The device can receive information about the action identified in the received ticket from at least one user of the group of users in response to provision of a determined key and the received ticket to the group of users. The device can provide the received information to client devices of user of the group of users to identify actions of other users of the group of users.

Abstract: Methods and systems for management of subscriber identities associated with user devices are described herein. The user device may enroll the user device to a server and lock a subscriber identity associated with the device by setting a password on the subscriber identity. If a credential entered by a user is verified, the subscriber identity associated with the device may be unlocked. Alternatively, the user device may retrieve one or more identities associated with the user, the user device and/or the subscriber identity. A server may register the one or more identities with a database. If the user device sends a request to connect to the network, the server may verify the one or more identities retrieved by the user device to determine whether to grant access from the user device to the network.
