  • Publication number: 20210294803
    Abstract: This disclosure relates generally to a method and system for extraction of SQL queries in an application. Various conventional approaches models SQL query extraction at a specific program point problem as an instance of string expression problem. Many string analysis based solutions are not scalable for large applications and those which are scalable do not account explicitly for the heap based flow. In an embodiment, the disclosed method and system utilizes a multi-criteria slicing based model which takes into account the data flowing through heap and contributing to SQL queries generation.

    Abstract: Method and system for analyzing unstructured data for compliance enforcement is disclosed. The system provides a comprehensive compliance enforcement platform, which enables purpose based data processing in an enterprise to support automatic discovery of purposes and linking between data fields and purposes. The system creates a single view of data associated with the data subject for enforcing the data subject's right for data protection and privacy. The system supports database like transactions for unstructured data over web and ensures Atomicity, Consistency, Isolation and Durability (ACID) properties of these transactions. Thus, the system creates a uniform data layer or a web view for data residing in the unstructured and semi-structured data, spread across the enterprise. The transactions on the unstructured data include READ operation, UPDATE operation, and DELETE operation using hypertext transfer protocol (http) over the unstructured data.

  • Publication number: 20210211291
    Abstract: Conventionally, biometric template protection has been achieved to improve matching performance with high levels of security by use of deep convolution neural network models. However, such attempts have prominent security limitations mapping information of images to binary codes is stored in an unprotected form. Given this model and access to the stolen protected templates, the adversary can exploit the False Accept Rate (FAR) of the system. Secondly, once the server system is compromised all the users need to be re-enrolled again. Unlike conventional systems and approaches, present disclosure provides systems and methods that implement encrypted deep neural network(s) for biometric template protection for enrollment and verification wherein the encrypted deep neural network(s) is utilized for mapping feature vectors to a randomly generated binary code and a deep neural network model learnt is encrypted thus achieving security and privacy for data protection.

  • Publication number: 20210182990
    Abstract: System and method for contract management in a data marketplace are disclosed. In an embodiment, the system performs refactoring of a contract, during which the system extracts terms and conditions from the contract and generates a simplified view of the contract. The system further performs a requirement validation based on the contract, during which the system determines features of data entity matches requirements specified by a first party or not, based on domain specific ontologies. If the data entity features are not matching with the requirements, then the system fetches one or more relevant attributes from a list of ontologies, verifies whether the features of entity along with the selected feature(s) satisfy the requirements or not. The system accordingly generates an agreeable requirement document as output of the requirement validation.

  • Publication number: 20210176266
    Abstract: This disclosure relates generally to selection of cloud service providers in a multi-cloud. The selection of cloud service providers (CSPs) in a multi-cloud environment is challenging as it depends on multiple criteria such as security, usability, latency, and service cost. In an embodiment, for each CSP and multi-CSP combination, two decision problems are solved; namely, a VM selection problem and a cloud region selection problem, taking latency requirement and DR laws constraints into consideration. By solving the VM selection and CC selection problems, the service cost and the user to cloud region mapping are estimated. Using said estimates and other qualitative criteria, a multi-cloud multi-criteria decision problem is solved using MCDM techniques to rank the CSP combinations for each application. Based on the ranks and a constraint on a service cost of the entity one of a CSP and a CSP combination is selected for each application.

  • Patent number: 10791133
    Abstract: This disclosure relates generally to malware detection, and more particularly to system and method for detecting and mitigating ransomware threats. For a User Equipment being monitored, the system performs a behavior analysis of corresponding file system to determine whether any anomalous behavior that would amount to a ransomware threat is associated with flies associated with the file system change, if present, then the system virtualizes the file system on the fly. If information pertaining to the identified anomalous behavior is present in any of the reference databases in the system, then all the I/O calls are terminated or the file system is virtualized for rest of the session. If data pertaining to the identified anomalous behavior is not found in any of the associated databases, then new behavioral features and structural patterns of the identified anomalous behavior and the associated processes are extracted, and the reference databases are updated accordingly.

  • Patent number: 10691884
    Abstract: System and method for cheque image data masking are disclosed. In an example, a cheque image and a data file are received, the data file includes data records with values corresponding to sensitive data fields in the cheque image. Further, a template cheque image matching to the cheque image and redacted information associated with the template cheque image are obtained. Furthermore, a blank image snippet is generated for each sensitive data field in the cheque image based on a part of the obtained information about sensitive fields. Moreover, values corresponding to each sensitive field from the input data file are written to the blank image snippet based on the remaining information about sensitive fields. Also, the template cheque image is updated with the image snippet. Data of non-sensitive fields in the cheque image is then copied to the template cheque image, thereby facilitating cheque image data masking.

  • Patent number: 10423618
    Abstract: A system and method are provided for enforcing user policies on database. In one aspect a user policy and/or enterprise policy is predefined and mapped to the column of the database. Further, the query is run through a query parsing module, the result is sent to a query analyzing module to analyze the sensitivity of each query. A query rewriting module rewrites the query and the rewritten query is sent to the database. A sensitive tree is generated using database metadata, which is used during query analysis and query re-writing. In cases the original query does not contain any set operators the rewritten query is executed on the database and results are displayed as per the user policy. The cases where the original query comprises set operators a function called merger is implemented in the database or at the proxy server and data is displayed as per the user policy.
