    The aim of this system is to track a person of interest in real time based on scenes obtained from camera modules. This system avoids potential human errors as we are using automatic monitoring. It is a histogram based real time tracking system. Moving objects are detected using background subtraction.Moving object detection, recognition and tracking are basic steps in processing video frames

    Enhanced Cauchy Matrix Reed-Solomon Codes and Role-Based Cryptographic Data Access for Data Recovery and Security in Cloud Environment

    In computer systems ensuring proper authorization is a significant challenge, particularly with the rise of open systems and dispersed platforms like the cloud. Role-Based Access Control (RBAC) has been widely adopted in cloud server applications due to its popularity and versatility. When granting authorization access to data stored in the cloud for collecting evidence against offenders, computer forensic investigations play a crucial role. As cloud service providers may not always be reliable, data confidentiality should be ensured within the system. Additionally, a proper revocation procedure is essential for managing users whose credentials have expired.  With the increasing scale and distribution of storage systems, component failures have become more common, making fault tolerance a critical concern. In response to this, a secure data-sharing system has been developed, enabling secure key distribution and data sharing for dynamic groups using role-based access control and AES encryption technology. Data recovery involves storing duplicate data to withstand a certain level of data loss. To secure data across distributed systems, the erasure code method is employed. Erasure coding techniques, such as Reed-Solomon codes, have the potential to significantly reduce data storage costs while maintaining resilience against disk failures. In light of this, there is a growing interest from academia and the corporate world in developing innovative coding techniques for cloud storage systems. The research goal is to create a new coding scheme that enhances the efficiency of Reed-Solomon coding using the sophisticated Cauchy matrix to achieve fault toleranc

    A Comparative Study: Change Detection and Querying Dynamic XML Documents

    The efficient management of the dynamic XML documents is a complex area of research. The changes and size of the XML documents throughout its lifetime are limitless. Change detection is an important part of version management to identify difference between successive versions of a document. Document content is continuously evolving. Users wanted to be able to query previous versions, query changes in documents, as well as to retrieve a particular document version efficiently. In this paper we provide comprehensive comparative analysis of various control schemes for change detection and querying dynamic XML documents

    Study of freshwater fish fauna and water quality at Paintakli dam from Buldhana district, (M.S) India

    Present investigation is carried out during the study period Jun 2010 to May 2011 to study the fish fauna from Paintakli dam. It is a perennial water resource which used for human consumption, agriculture and fisheries in taluka Chikli and Mahekar, district Buldhana. It is situated approximately 45 km from district Buldhana. In the present study it was observed that the ichthyofauna belong to 07 order 10 families, 19 genus and 21 species, were Cyprinidae family is dominant with 10 (47.61%) species followed by Channidae and Mastacembelidae with 02 (9.52%) species, Balitoridae, Bagridae, Clariidae, Belonidae, Notopteridae, Cichlidae, and Poecilidae contribute 01(4.76%) species each. Finally it may be concluded that the water parameters are within permissible limit and support  fish diversity  of Paintakli dam were Cyprinidae family which is dominant and still in a position to set a good example of conservation and sustainable management of fish and fishery.&nbsp

    An Optimistic Approach for Clustering Multi-version XML Documents Using Compressed Delta

    Get PDF
    Today with Standardization of XML as an information exchange over web, huge amount of information is formatted in the XML document. XML documents are huge in size. The amount of information that has to be transmitted, processed, stored, and queried is often larger than that of other data formats. Also in real world applications XML documents are dynamic in nature. The versatile applicability of XML documents in different fields of information maintenance and management is increasing the demand to store different versions of XML documents with time. However, storage of all versions of an XML document may introduce the redundancy. Self describing nature of XML creates the problem of verbosity,in result documents are in huge size. This paper proposes optimistic approach to Re-cluster multi-version XML documents which change in time by reassessing distance between them by using knowledge from initial clustering solution and changes stored in compressed delta. Evolving size of XML document is reduced by applying homomorphic compression before clustering them which retains its original structure. Compressed delta stores the changes responsible for document versions, without decompressing them. Test results shows that our approach performs much better than using full pair-wise document comparison
