  • Patent number: 8140550
    Abstract: Multimedia content usage is on the rise and hence, it is becoming increasingly necessary to automatically analyze the multimedia content in order enhance the effective applicability and usage of the content. The richness of a multimedia content demands multi-fold analysis of the content and further, this richness also leads to openness and vastness. Hence, the outcome of the multiple analyses techniques needs to be carefully analyzed in order to avoid limited or inconsistent content description. A system and method for bounded analysis of multimedia using multiple correlations addresses the issues related to richness and vastness of a multimedia content to enable describing of the multimedia content in a maximally consistent manner. Such a content description is very useful in the semantic characterization of multimedia.

  • 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.

  • 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.

  • Publication number: 20110107090
    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.

  • 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.

  • Publication number: 20100167709
    Abstract: Peer to peer interactions are a popular way of social networking. Such peer to peer interactions play an important role in (a) obtaining relevant and latest information; (b) obtaining relevant experiential information; (c) obtaining of relevant opinions on, say, products; (d) collaborative problem solving, and so on. Consider a scenario of classified ads: a user visiting a portal through a mobile phone to decide on buying of a product can be well assisted by facilitating peer to peer interactions. In many situations, it is required to make the right selection of peers in order to be able to obtain the right information, and furthermore, voice is a preferred mode of interaction if mobile phones are used in peer to peer interactions. Also, in peer to peer interactions, anonymity is important in order to protect the privacy of the peers.

  • Publication number: 20100122297
    Abstract: Modeling user likes and dislikes is an important aspect of target marketing. Typically, a user performs several activities related to a particular domain, and the outcomes of these activities indicate the extent of liking/disliking that resulted on account of these activities. Further, many of these activities are performed on a routine basis. The problem of user likes modeling is to analyze these various activities performed by the user and the solution is to arrive at a likes/dislikes model of the user. Such a likes/dislikes model helps in, for example, ad targeting in the context of TV viewing and cross-selling in the case of mobile services.
