Patents by Inventor Sergey Smirnoff

Sergey Smirnoff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11240219
    Abstract: A portable communication device may include a mobile application executing in an application execution environment and a secure application executing in a trusted execution environment. The secure application may receive, from the mobile application, a storage request to store sensitive data. The storage request may include an encrypted data type identifier and an encrypted sensitive data. The secure application may decrypt the encrypted data type identifier and the encrypted sensitive data using a transport key, and re-encrypt the sensitive data using a storage key. The re-encrypted sensitive data can then be stored in a memory of the portable communication device which is outside the trusted execution environment.

  • Publication number: 20200279258
    Abstract: Systems, methods, and computer readable media are provided for improving the usability of a cryptogram generated in a first cryptographic protocol such as triple-DES. The methods may generate a first cryptogram using a first identifier in a first cryptographic protocol, stored in a key store within an insecure memory of the mobile communication device, generate, within a secure memory of the mobile communication device, a second cryptogram using a second identifier in a second cryptographic protocol, stored in the secure memory, combining, the first cryptogram and a number of characters of the second cryptogram equal to the length of the first cryptogram to generate a third cryptogram and transmitting the third cryptogram to an payment processing network to validate a transaction. A transaction associated with the third cryptogram may be validated by an authorization entity or an issue entity.

  • Patent number: 9917889
    Abstract: According to various example embodiments, a request transmitted from a client and directed to a service application is intercepted. A logical database (DB) host specified by a hint value included in the request is then identified. Moreover, a target physical DB host is identified, based on the identified logical DB host and DB host mapping information. Thereafter, the request is routed to an instance of the service application co-located with the identified target physical DB host at a particular data center.
