  • Publication number: 20210357770
    Abstract: Techniques are disclosed relating to dynamically determining a data load process usable with a decision service for responding to requests to the decision service. The data load process may be selected from either a full data load process that loads data needed for all the rules in the decision service, or a selective data load process that loads data needed for a subset of the rules in the decision service according to embodiments. The decision service may determine the data load process to implement based on an evaluation of a decision blueprint in response to receiving the request, where the decision blueprint includes a set of rules interconnected by flow paths. Evaluation of properties of the rules and flow paths based on input data in the request may be used to determine the data load process to implement. Overall, this results in faster execution times in various circumstances.

  • Patent number: 9805350
    Abstract: The invention relates to a system and method providing access of one or more heterogeneous digital contents to at least one offline Digital Rights Management (DRM) user by a DRM server. This invention involves establishing the trust relationship among the DRM server, DRM client, user's machine and the end user by means of digital certificate. The server generates protected digital content by means of using a standard encryption algorithm. The invention further involves determining whether a license for accessing the protected file is requested by the legitimate user, and if so, generating a license consisting the user rights and the protected decryption key to be downloaded by legitimate user. The DRM client decrypts the protected file using a decryption key of the license, and renders the content to the end user by calling the appropriate and customized viewer during consumption.

  • Patent number: 9805019
    Abstract: The described technologies can be used for masking one or more heterogeneous digital contents. One or more heterogeneous digital contents can be received from one or more data sources. Further, the received one or more heterogeneous digital contents can be parsed by a first parser unit to obtain a portable format data. The portable format data can be a homogeneous digital content arranged in one or more layers. Further, masking of the portable format data can be performed by a masking unit. A masking methodology can be applied based on selection of one or more rules from a plurality of rules to obtain a masked portable format data. Further, reverse-parsing of the masked portable format data can be performed by a second parser unit to obtain a masked data. Structure of the received one or more heterogeneous digital contents remains preserved.

  • Publication number: 20140047557
    Abstract: The invention relates to a system and method providing access of one or more heterogeneous digital contents to at least one online Digital Rights Management (DRM) user by a DRM server. This invention involves receiving digital contents from the publishers and those digital contents are encrypted and user rights are granted to access the contents by the publisher. The DRM server stores the decryption information, user rights and user information in a repository. After authenticating the user who is connected with the DRM server through a DRM client, the DRM server sends a license to the DRM user which includes the decryption information and the user rights. The DRM client decrypts the contents based on the license information in the memory of the user's computer device and thus the content and the license are not locally stored.

  • Publication number: 20130184462
    Abstract: The present invention relates to the development of a virtual screening model for predicting antipsychotic activity using quantitative structure activity relationship (QSAR), molecular docking, oral bioavailability, ADME and Toxicity studies. The present invention also relates to the development of QSAR model using forward stepwise method of multiple linear regression with leave-one-out validation approach. QSAR model showed activity-descriptors relationship correlating measure (r2) 0.87 (87%) and predictive accuracy of 81% (rCV2=0.81). The present invention specifically showed strong binding affinity of the untested (unknown) novel compounds against anti-psychotic targets viz., Dopamine D2 and Serotonin (5HT2A) receptors through molecular docking approach. Theoretical results were in accord with the in vitro and in vivo experimental data. The present invention further showed compliance of Lipinski's rule of five for oral bioavailability and toxicity risk assessment for all the active Yohimbine derivatives.
