Abstract: A framework referred to as COmposition fRamework for chaNge management (CORNET) may integrate re-usable abstraction, modular composition with plug-and-play capabilities, or automated translation of high-level change management intent into low-level implementations and mathematical models. CORNET may use real-world data collected from cellular networks (e.g., 4G or 5G) and virtualized services, such as virtual private networks (VPN) and software defined wide area networks (SDWAN) running in the cloud.

Abstract: Aspects of data management are described. During an update procedure for serially updating a cluster of storage nodes, a storage node of the cluster of storage nodes may enter a quiescent state. While in the quiescent state, the storage node may refrain from obtaining new jobs and may continue to execute jobs that were initiated at the storage node prior to entering the quiescent state. The storage node may enter the quiescent state while another storage node enters an update state for installing the update version. The storage node may also post, to a job queue, jobs running at the storage node that are terminated at an end of the quiescent state.

Abstract: The invention secures contactless payment cards against misuse at ‘unattended type’ terminal devices having near field communication capabilities. The invention involves receiving from a communication device a first unique identifier associated with a contactless payment card, and a second unique identifier associated with the communication device. Transmission of the first unique identifier and the second unique identifier from the communication device is implemented in response to the communication device detecting a contactless card tap event, and the communication device retrieving the first unique identifier from the contactless payment card. The invention involves selectively implementing one of a first payment authorization communication flow and a second payment authorization communication flow.

Abstract: A method for facilitating payment transactions includes receiving, by a server, a flash code request indicative of a transaction amount. A flash code associated with the transaction amount is communicated by the server to the payer device. The flash code is encoded into a flash pattern at the payer device and communicated to a payee device of a payee for executing a payment transaction between the payer and the payee. A first request for the payment transaction is received by the server from the payee device. The first request includes the flash code obtained by decoding the flash pattern at the payee device. The flash code included in the first request is validated by the server. Based on successful validation of the flash code, the transaction amount is deducted from a payer account of the payer and credited to a payee account of the payee.

Abstract: Embodiments provide methods and systems for sharing a user consent associated with user consent among applications. Method performed by server system includes storing consent token associated with user in a database based upon receiving consent from the user on the first application to utilize user credential data for subsequent transactions in connection with interaction between a user device and a first application service provider. The method includes receiving a request to access the consent token associated from a second application service provider associated with a second application accessible on the user device, determining whether the second application service provider is able to access the consent token associated with the first application based on access level data set by the first application service provider of the first application for accessing the consent token and allowing access of the consent token to the second application based on the determining step.

Abstract: Method and System for Facilitating Secure Payment Transactions A method for facilitating payment transactions includes receiving, by a server, a flash code request indicative of a transaction amount. A flash code associated with the transaction amount is communicated by the server to the payer device.

Abstract: A method and a system for facilitating reuse or recycling of a packing bag are provided. A server links one or more details of the packing bag with a user identifier of a user based on an issuance of the packing bag to the user. The packing bag is associated with an identity tag that stores the one or more details of the packing bag. The server detects an occurrence of a first event associated with the packing bag. The first event corresponds to the reuse of the packing bag by the user or submission of the packing bag by the user for recycling. Based on the detection of the first event, the server credits one or more reward points to a reward point account that is associated with the user identifier of the user. The reward points credited to the reward point account are redeemable by the user.

Abstract: A transaction card comprises a piezoelectric chip configured to detect an impact applied to at least a portion of the transaction card, and generate an electrical pulse signal based on the detected impact. A processing circuitry of the transaction card is coupled to the piezoelectric chip. The processing circuitry, upon powering on, is configured to enable data exchange between the transaction card and a terminal device for executing a card-based transaction at the terminal device. The data exchange is enabled only when a magnitude of the electrical pulse signal exceeds a threshold value, thereby preventing unwanted data transfer from the transaction card.

Abstract: Embodiments provide methods and systems for controlling payment transactions in a payment card using a companion payment application installed on a user device. The payment application and the payment card may be provided by an issuer server. Using the payment application, the number of transactions allowed on the payment card or an amount limit is set for the payment card. The payment application is used to set, reset, change the value of a counter in the card, which determines the number of allowed transactions. When the user attempts to make a transaction at a POS terminal, the payment card reads the value of counter, and if the value is not equal to a threshold value, the payment card exchanges data with the POS terminal and updates the value of the counter. The payment card is precluded from transaction when value of the counter is equal to threshold value.

Abstract: Embodiments provide methods and systems for facilitating online shopping while watching multimedia content on an electronic device. The method includes receiving an input, from a controller, from a user interested in purchasing at least one item using a machine-readable code displayed in a scene of the multimedia content. The scene comprising the machine-readable code. The machine-readable code comprising payment information for purchasing the item. The method further includes capturing at least one screenshot of the scene comprising the machine-readable code without interrupting display of the multimedia content. The method also includes identifying the at least one machine-readable code in the at least one screenshot of the scene. Upon identifying the at least one machine-readable code the method includes extracting the at least one machine-readable code from the at least screenshot of the scene for processing a payment based on payment information present in the machine-readable code.
