Title: Securely invoking a REST API at an application server using Digest Access Authentication
Inventor: LAI RAY Y
IPC: G06F17/30
Filed: 2009-03-06
Abstract: A client establishes a first secure communication channel with an application server and sends a first request to the server, using the channel, to invoke a REST (Representational State Transfer) API (Application Programming Interface). In response to authenticating a user with an authentication system, perhaps over a second secure communication channel as redirected by the server, the client receives a security token. In response to the first request, the server sends a nonce (number used once) and a timestamp to the client. Using the security token, the nonce and the timestamp, perhaps by applying a cryptographic hash function, the client determines a security token digest. The client sends the security token digest, using the first secure channel, as part of a second request to the server to invoke the REST API. The server validates the security token digest and, if it is valid, generates and sends output data to the client which receives and stores the data.

Title: Method of Assessing Hydrocarbon Source Rock Candidate
Inventor: LOSETH HELGE
IPC: G01V1/30
Filed: 2009-09-07
Abstract: A method of assessing a hydrocarbon source rock candidate uses seismic data for a region of the Earth. The data are analysed to determine the presence, thickness and lateral extent of candidate source rock based on the knowledge of the seismic behaviour of hydrocarbon source rocks. An estimate is provided of the organic content (TOC) of the candidate source rock from acoustic impedance, based on a predetermined relationship between acoustic impedance and organic content (from rock sample analysis or well logs, for instance). An estimate of the hydrocarbon generation potential of the candidate source rock is then provided from the thickness and lateral extent of the candidate source rock and from the estimate of the organic content. The analysis of the data may involve an amplitude versus offset (AVO) analysis. The method may comprise basin modeling based on the seismic characteristics of the candidate source rock, and controlling exploration or production based on the model.
