  • Patent number: 8538958
    Abstract: Personalized services and targeted services demand the exploitation of context—say, context of an environment, context of a product, context of a service, and context of a customer or user or individual. In order for the personalized and targeted services to have a greater impact, the identified context used by a context aware processing engine needs to be accurate and current. Such an up-to-date context is called as context map and a system and method for generating a customer-specific context map involves the processing of customer transactions, abstracting and generalizing these transactions into entities, and inter-relating these entities. The context map, for example, is useful in ad targeting in mobile environments, and in quicker and efficient problem resolution in contact center environments.

  • Patent number: 8156546
    Abstract: Enterprise users access several applications and services routinely to carry out their work-related activities on a day-to-day basis. These applications and services could be hosted within an enterprise or on a third-party data center. The enterprise users login into the applications and services so as to gain access to the applications and services. In the case of single sign-on, it is expected that the users authenticate once to a specific application/service/system and obtain access to any other application/service/system. In such a scenario, it is important to ensure that during the course of this authenticated access grant, the right users are provided access to right information. This is achieved by a re-authentication system that demands minimum re-authentication effort from “right” users and maximum re-authentication effort from “non-right” users. A system and method of on the fly re-authentication involves a novel challenge-response mechanism.

  • Patent number: 8090670
    Abstract: Remote control units are used to interact with a variety of devices. Modeling of the usage of a remote control unit while interacting with a device helps in (a) redesigning the remote for better usability; (b) dynamic adapting of the remote to provide improved interactions; and (c) characterizing the usage behaviors. In particular, it is very popular to use remote control units to interact with TVs and PVR devices. A system and method for the modeling of a remote usage involves the use of both pre-defined models and discovered models. Specifically, a pattern of usage of a remote control unit is abstracted to be one of either a pre-defined model or a discovered model. The model discovery involves the process of generalization based on a set of particular remote control unit usage patterns. The labels associated with the models help in characterizing the remote control unit usage patterns.

  • Patent number: 8086692
    Abstract: Real-time delivery of multimedia content puts extreme demand on both computational and network resources. Many a times, the requirement is to handle multiple such delivery requirements and as a consequence, the overall delivery efficiency gets affected. Another dimension of complexity is that (a) the multimedia content to be delivered may not always be highly reliable, and (b) the network may also be not highly reliable. In such a situation, it becomes even more difficult to satisfy the quality of service requirements. When content to be delivered to multiple destinations is available at multiple sources, there is an opportunity to overcome the above mentioned complexity. The system and method for efficient delivery in a multi-source multi-destination network involves pulling of data from the multiple sources by measuring quality of service and reliability parameters, and efficiently loading the systems and the network in a cooperative manner.

  • Patent number: 8068431
    Abstract: IP networks carry packets that consist of headers and payloads. Typical traffic analysis systems at layer 3 process packet headers in order to obtain as much information about the traffic as possible. However, performing of deep packet analysis requires the processing of packet payloads as well. Another important requirement of layer 3 processing is the need to process the payloads at wire speeds. A system and method for deep packet inspection at layer 3 involves (a) an approach for packet payload processing; (b) accounting for out of order arrival of packets; (c) an approach for partial match analysis so as to be able to analyze the traffic flows when only partial information is available; and (d) an approach for effective payload processing for attempting to achieve wire speed processing.

  • Patent number: 8068677
    Abstract: Video processing in general and image processing in particular is a very complex process. This is more so when the analysis is required to extract information from the images for providing of the same directly or indirectly to the users. This additional complexity is due to the direct competition with users who are used to analyzing of the images both syntactically and semantically. One of the ways to contain the complexity of image analysis is to exploit the domain semantics during image processing. A system and method to help in semantics based image processing involves the identification of one or more domain relevant semantic hierarchies and using of the same during image processing.

  • Publication number: 20110010590
    Abstract: Enterprises are fast moving towards restructuring their IT infrastructure by exploiting the emerging models of data centers. In one extreme, the whole of application, storage, and network needs of an enterprise are to be managed by third party data centers. While the use of third party data centers is an attractive proposition for enterprises, it can potentially put their intellectual property in the form of applications and data assets under threat. There is a need for a system that is a part of a data center but owned by an enterprise that provides a single point of entry and exit for interacting and communicating with the data center and the enterprise relies on this system to obtain an insight into the functioning and behavior of the data center.

  • Patent number: 7751334
    Abstract: Networks carry various kinds of traffic and ISPs are keen to analyze the traffic so as to be able to support QoS on the distinct traffic flows. Traffic can be broadly categorized into two types: plain traffic and encrypted traffic. Further, each of these traffic types is based on either a standard protocol or a proprietary protocol. While it is fairly straightforward to analyze traffic that are based on standard protocols, it is extremely difficult to analyze encrypted traffic based on proprietary protocols. A system for Skype traffic detection involves analyzing encrypted traffic based on proprietary peer to peer protocol. The proposed approach is based on building Skype traffic models and using the same to determine Skype traffic in the network traffic.
