Abstract: Methods of obtaining input on a physical input device are provided. A method includes superimposing an image of a virtual keypad over an image of a touchscreen keypad, wherein the virtual keypad device has a different layout than the touchscreen keypad, mapping a first input on the touchscreen keypad to a second input on the virtual keypad, wherein the second input is different from the first input, and displaying on the touchscreen keypad a visually encoded symbol that defines a mapping from the touchscreen keypad to the virtual keypad, wherein mapping the first input on the touchscreen keypad to the second input on the virtual keypad is performed in response to the visually encoded symbol.

Abstract: A method, non-transitory computer readable medium and apparatus for decrypting a document are disclosed. For example, the method captures a tag on an encrypted document, transmits the tag to an application server of a communication network to request a per-document decryption key, receives the per-document decryption key if the tag is authenticated, and decrypts a portion of the encrypted document using a temporary decryption key contained in the tag, the tag decrypted with the per-document decryption key.

Abstract: Methods of obtaining input on a physical input device are provided. A virtual input device is superimposed over the physical input device. The virtual input device has a different layout than the physical input device, such that a first input on the physical input device is mapped to a different input on the virtual input device. In another aspect, methods of securing a transaction according include displaying a first input screen to a user, encrypting a scrambling key using a public key, the scrambling key defining a second input screen that has a different layout from the first input screen, transmitting the encrypted scrambling key to a user device, receiving an input from the user device, and mapping the input to the second input screen.

Abstract: A method, non-transitory computer readable medium and apparatus for securing user input and/or output on a mobile endpoint device. For example, the method receives an input on the mobile endpoint device, encrypts and authenticates the input in a trusted domain of the mobile endpoint device executing an application and sends the input that is encrypted and authenticated to an untrusted domain of the mobile endpoint device over a secure channel.

Abstract: Methods, non-transitory computer readable media and apparatuses for decrypting an image are disclosed. For example, a method captures a portion of an encrypted image and decrypts the portion of the image using a decryption key. The portion of the image contains partial information for an adjacent portion of the image. The method then displays the portion of the image that is decrypted and also displays the adjacent portion of the image using the partial information for the adjacent portion of the image. Another method includes capturing a first portion of an image that is encrypted using a first key and a second key, decrypting the first portion of the image using a first key and displaying the first portion of the image that is decrypted.

Abstract: Embodiments are directed towards communicating using a mobile device that performs actions including. A mobile device may be provisioned with an access point such that a provisioning key and a provisioning token for each of the provisioned access points may be stored on the mobile device. The mobile device may be determined to be in the presence of a provisioned access point based on the provisioning key and an advertising nonce. The advertising nonce may be encrypted with the provisioning key. A communication channel between the mobile device and the access point may be established based on a session nonce, the advertising nonce, and the provisioning key. A session key may be generated based in part on the advertising nonce and a message counter. And, encrypted message packets that include a message and a message authentication tag may be communicated to the access point.

Abstract: Concepts and technologies are disclosed herein for verifying sender information. According to various embodiments of the concepts and technologies disclosed herein, a verification service can determine, receive a request, or receive a call to verify sender information associated with data. The server computer generates and delivers a verification message to a sender device in response to determining that sender information verification is to be provided. The server computer receives a response indicating if the data was sent by the sender device. If the response indicates that the sender device did not send the data, the server computer can block delivery of the data, generate alarms or alerts, take other actions, and/or take no action. If the response indicates that the sender device sent the data, the server computer can deliver the data, provide a verification response to the recipient device, take no action, and/or take other actions.

Abstract: Concepts and technologies are disclosed herein for filtering network traffic using protected filtering mechanisms. An indication that traffic is to be filtered can be received, and a hash key, a signature representation, and an obfuscated signature can be identified or generated. The hash key and the signature representation can be provided to a first device without exposing the contents of the signature to the second device, and the obfuscated signature can be provided to a second device without exposing the contents of the signature to the second device. The first device and the second device can execute independent operations to collectively determine if the traffic is to be filtered.

Abstract: To verify compliance with a data access policy, a query result including data specified by a requesting entity and a representation of a data access policy is received from a database. Based on the representation of the data access policy included in the query result, it is verified whether the requesting entity is permitted to access the data included in the query result. Transmission of the data included in the query result to the requesting entity is controlled responsive to the verification. Related methods, systems, and computer program products are also discussed.
