Abstract: A system for performing ransomware scan is presented. The system includes a snapshot access module configured to access a base snapshot corresponding to a dataset. The system further includes a log access module configured to access a log of modified metadata and/or data blocks from a data back-up server corresponding to a subsequent snapshot versus the base snapshot. The system moreover includes an incremental block module configured to download one or more incremental metadata and/or data blocks from the data back-up server based on the log of modified metadata and/or data blocks. The system further includes a snapshot write module configured to write the one or more incremental metadata and/or data blocks on the base snapshot to generate an incremental snapshot. The system furthermore includes a ransomware scan module configured to scan the incremental snapshot to check for ransomware. A related method is also presented.

Abstract: An aspect of the present invention enables users to avail specialized services using missed calls. In one embodiment, a missed call server on receiving an indication that a missed call has been placed by a user to a phone number, determines the specialized service corresponding to the phone number, and then sends a data to the service provider offering the determined service. The service provider then delivers the specialized service (sought to be availed) to the user. One of the specialized services is the delivery of content to the user. Thus, a user is enabled to access different contents by placing missed calls to the appropriate phone numbers.

Abstract: An aspect of the present invention facilitates formation of groups using missed calls. In an embodiment, upon receipt of a first missed call to a pre-specified number from a first user, a missed call server allocates a first phone number to a new group. Upon receiving missed calls to such allocated number, the corresponding callers (i.e., the phone numbers of the callers) are added to the group. According to another aspect of the present invention, different phone numbers are allocated for different groups, and the members are added in each group, in response to missed calls to the corresponding numbers. Additional management tasks such as provide group owner the ability to approve/reject the addition/removal requests, formation of sub-groups, etc., are also facilitated based on missed calls.

Abstract: The various embodiments herein provide a dongle device with a communication module for a secure electronic transaction. The dongle device comprises housing provided with a slot for inserting a magnetic stripe card, a slot for inserting a contact type card, a communication module such as a Wireless module or a Bluetooth module or a mobile communication module or a zigbee module, a key pad, a connector, a cover for safeguarding the connector, a stylus, a universal serial bus (USB) port, a processor and a display. The communication module is a pluggable module to the dongle device. The card is read and the card data are transmitted through the supersonic frequencies or spread spectrum signals to a payment gateway server. The communication module links a transaction originated in a cloud computing server with a payment gateway server through a mobile device to complete a financial transaction.

Abstract: The various embodiments herein provide a dongle device with tamper proof characteristics for a secure electronic transaction. The dongle device comprises a housing which includes a first half comprising a main circuit board and a second half comprising a secondary circuit board, a slot for swiping a magnetic stripe card, a slot for inserting a contact type card, a communication module, a key pad, a connector, a cover for safeguarding the connector, a stylus, a universal serial bus (USB) port, a processor and a display. The processor continuously monitors a connection between the main circuit board and the secondary circuit board and kills the dongle device when processor detects a tampering. The first half and the second half of the dongle device are ultrasonically sealed together. The main circuit board and the secondary circuit board are electrically and electronically connected through a compressible connector.

Abstract: The various embodiments herein provide a dongle device with rechargeable power supply for a secure electronic transaction. The dongle device comprises a slot for swiping a magnetic stripe card, a slot for inserting a contact type card, a rechargeable battery, a recharging circuit, a key pad, a key pad cover, a connector, wherein the connector is an audio jack, a cover for safeguarding the connector, a stylus, a universal serial bus (USB) port, a processor and a display. The rechargeable battery is powered by the recharging circuit when a residual battery level of the rechargeable battery falls below a preset value. The key pad is used to enter PIN and the key pad cover prevents an onlooker from viewing and learning the PIN entered by a user.

Abstract: The various embodiments herein provide a system for a secure electronic transaction. The system comprises a dongle connected to a computing device for reading an electronic card data, a client application running on the client device for collecting a transaction information from a customer, a service provider system connected to the computing device through a first communication network for transmitting the collected transaction information and the audio signal from the computing device to the service provider system, a production server located at the service provider system for processing the received card data, a payment server for processing the audio signal, a second communication network for transmitting a processed card data from the production server to a payment system and a payment gateway running on the payment system for interfacing with the service provider system. The payment system performs the financial transaction by authenticating the customer and a merchant.
