摘要:
A communication device is configured to receive messages. The communication device may comprise a display screen upon which messages are displayed. A microprocessor configured to execute at least one message management program on the communication device, filters incoming messages. The message management program comprising a message filter application filters received messages based on a comparison of sender identification data associated with a received message to approved sender identification data.

Embodiments of the systems, devices, and methods described herein generally facilitate the display of a barcode at a computing device for capture by another computing device. In accordance with one example embodiment, a barcode is generated at a first computing device, the barcode is displayed on a display screen associated with the first computing device, and one or more display properties of the barcode are dynamically modified while it is displayed at the first computing device until the barcode is successfully captured (e.g. by a camera) at a second computing device.

A method for secure bidirectional communication between two systems is described. A first key pair and a second key pair are generated, the latter including a second public key that is generated based upon a shared secret. First and second public keys are sent to a second system, and third and fourth public keys are received from the second system. The fourth public key is generated based upon the shared secret. A master key for encrypting messages is calculated based upon a first private key, a second private key, the third public key and the fourth public key. For re-keying, a new second key pair having a new second public key and a new second private key is generated, and a new fourth public key is received. A new master key is calculated using elliptic curve calculations using the new second private key and the new fourth public key.

The present disclosure relates generally to the authentication of contactless payments attempted by a device having embedded contactless payment functionality. In particular, the disclosure is directed to systems and methods that utilize authentication schemes that already exist on a device in which the contactless payment functionality is embedded. One example of such authentication schemes is the use of password protection to lock or unlock the device in which the contactless payment functionality is embedded. Using the password protection functionality may provide varying levels of authentication protection based on the desires of the user. A number of exemplary uses of such a method and apparatus are disclosed herein.

A method for processing security communication protocol compliant signed receipts at a mobile communication device linked to a host system is provided. The host system receives an email message linked to a digital signature, and a signed receipt. The host system redirects the signed receipt to the mobile communication device. The host system determines if the email message is available at the mobile communication device, and if not, the host system retrieves the email message and redirects the email message to the mobile communication device. The mobile communication device can then verify the signed receipt based on the email message. Optionally, rather than the email message, the host system retrieves and/or recalculates data elements associated with the email message and required to verify the signed receipt, and redirects these data elements to the mobile communication device. A related system is provided, as well as server computer program for the host system, and device computer program for the mobile communication device.

Selecting and modifying the transmission rates and sizes of status update messages transmitted by a mobile communications device to a recipient application based on use of the updates by the recipient application improves resource utilization or accuracy. During one mode of operation, a mobile communications device transmits status messages using a conservative message transmission mode. This allows the mobile communications device to transmit a greater number of status updates for future processing by the recipient application while conserving resources. When the recipient application is actively processing status updates from the mobile communications device, the mobile communications device transmits the status messages using an accelerated message transmission mode with a different number of status updates in each status message and different delay between status messages, which may reduce delay or improve accuracy. Similarly, the mobile communications device may reduce the number of status updates transmitted by applying algorithm-based filters described herein based on the expected usage by the recipient application.

A method, computer system, and computer program product for generating state-driven role-based landing pages. An enterprise application user in a secure enterprise application environment provides user-specified content relevant to the user's role in the enterprise, and when the user invokes an enterprise application, initial screens displayed by the enterprise application are displayed as landing pages using the user-specified content. The method commences by validating an enterprise application user using a user profile and a security model where the security model serves to distinguish permitted or allowed enterprise application user activities from denied enterprise application activities. Once validated, then the method identifies a user's role or roles, and further, identifies the user's selection of subscriptions (e.g., subscriptions pertaining to content related to the user's role). Given the user role and the user's selection of subscriptions, systems keep track of user states to use when populating landing pages with subscription content.
摘要:
A system and method for associating message addresses with certificates, in which one or more secondary message addresses are identified and associated with a user-selected certificate that does not contain any e-mail addresses. In certain situations, a message may be encrypted using a certificate that does not contain an e-mail address that matches the e-mail address of the individual to which the message is to be sent, so long as the address to which the message is to be sent matches any of the message addresses associated with the certificate. The message addresses are saved in a data structure that resides in a secure data store on a computing device, such as a mobile device.
摘要:
A system for adding a redundancy check to an electronic message to discourage tampering and facilitate identification of altered messages provides a communication device for composing message content, a messaging module with a formatting and encoding layer for encoding the message content with header information in a series of message blocks, and an encryption layer for calculating a redundancy check value and inserting the value in one or more locations within the series of message blocks according a rule defined by a characteristic of the message content or the header information, and encrypting the message for delivery to a recipient. Upon receipt, the recipient communication device decrypts the message, extracts the redundancy check value from the message, and compares a calculated redundancy check value with the extracted redundancy check value to determine if the message had been altered before receipt.
