Traffic Signal: Management & Control System

Multimedia, Parallel And Distributed System, Web | Desktop Application

Traffic Signal: Management & Control System This innovative software projects is an effective traffic signal management project that allows for managing 4 way traffic signal management system. The system consists of 4 signals corresponding to each road. We here propose a density based traffic signal scheduling algorithm. The system is designed to manage traffic signal timings based on the density of traffic on its corresponding road. The system represents the traffic strength of a road graphically using traffic judgments. By measuring the traffic lined up on a particular road the signal timings are adjusted to let that particular way clear out and then the next populated one. The entire system works according to an algorithm that allows for smooth and efficient traffic flow across all four ways. It also consists…

Topic Detection Using Keyword Clustering

Data mining, Networking, Parallel And Distributed System, Web | Desktop Application

Topic Detection Using Keyword Clustering To find prominent topic in a collection of documents. We here propose a system to detect topic from a collection of document. We use an efficient method to discover topic in a collection of documents known as topic model. A topic model is a type of statistical model for discovering topics from collection of documents. One would expect particular words to appear in the document more or less frequently: “dog” and “bone” will appear more often in documents about dogs, “cat” and “meow” will appear in documents about cats, and “the” and “is” will appear equally in both. A document typically concerns multiple topics in different proportions; thus, in a document that is 10% about cats and 90% about dogs, there would probably be about…

Data Duplication Removal Using File Checksum

Multimedia, Parallel And Distributed System, Security and Encryption, Web | Desktop Application

Data Duplication Removal Using File Checksum Data duplication technology usually identifies redundant data quickly and correctly by using file checksum technique. A checksum can determine whether there is redundant data. However, there are the presences of false positives. In order to avoid false positives, we need to compare a new chunk with chunks of data that have been stored. In order to reduce the time to exclude the false positives, current research uses extraction of file data checksum. However, the target file stores multiple attributes such as user id, filename, size, extension, checksum and date-time table. Whenever user uploads a particular file, the system then first calculates the checksum and that checksum is cross verified with the checksum data stored in database. If the file already exists, then it will…

Secure Data Transfer Over Internet Using Image Steganography

Cloud Computing, Networking, Parallel And Distributed System, Security and Encryption, Web | Desktop Application

Secure Data Transfer Over Internet Using Image Steganography Steganography is the technique of hiding private or sensitive information within something that appears to be nothing be a usual image. Steganography involves hiding Text so it appears that to be a normal image or other file. If a person views that object which has hidden information inside, he or she will have no idea that there is any secrete information. What steganography essentially does is exploit human perception, human senses are not trained to look for files that have information inside of them. What this system does is, it lets user to send text as secrete message inside an image file, user uploads the image and enters the text to send secretly, and gives a key or a pass word to…

Improved Data Leakage Detection

Parallel And Distributed System, Security and Encryption, Web | Desktop Application

Improved Data Leakage Detection Data leakage detection techniques are built for users to track if data has been leaked and the trace the sources of data leakage. Many times we come across cases where leaked data is found at unauthorized places. For example we may find sensitive data stored on an unauthorized laptop or website. At such a time it becomes important to trace the source of data leakage. For this purpose we propose an improved data leakage detection technique to trace back sources of unauthorized leakage by using a strategy of data allocation across various agents. The strategy allows user to transfer data to users by considering receivers as agents who are allocated data along with some id based undetectable alterations. These alterations allow our system to trace back…

Panda: Public Auditing for Shared Data with Efficient User Revocation in the Cloud

Cloud Computing, Data mining, Parallel And Distributed System, Security and Encryption, Web | Desktop Application

Panda: Public Auditing for Shared Data with Efficient User Revocation in the Cloud With data storage and sharing services in the cloud, users can easily modify and share data as a group. To ensure shared data integrity can be verified publicly, users in the group need to compute signatures on all the blocks in shared data. Different blocks in shared data are generally signed by different users due to data modifications performed by different users. For security reasons, once a user is revoked from the group, the blocks which were previously signed by this revoked user must be re-signed by an existing user. The straightforward method, which allows an existing user to download the corresponding part of shared data and re-sign it during user revocation, is inefficient due to the…

BECAN: A Bandwidth-Efficient Cooperative Authentication Scheme for Filtering Injected False Data in

Parallel And Distributed System

BECAN: A Bandwidth-Efficient Cooperative Authentication Scheme for Filtering Injected False Data in Injecting false data attack is a well known serious threat to wireless sensor network, for which an adversary reports bogus information to sink causing error decision at upper level and energy waste in en-route nodes. In this paper, we propose a novel bandwidth-efficient cooperative authentication (BECAN) scheme for filtering injected false data. Based on the random graph characteristics of sensor node deployment and the cooperative bit-compressed authentication technique, the proposed BECAN scheme can save energy by early detecting and filtering the majority of injected false data with minor extra overheads at the en-route nodes. In addition, only a very small fraction of injected false data needs to be checked by the sink, which thus largely reduces the burden…

Privacy-Preserving Updates to Anonymous and Confidential Databases

Parallel And Distributed System, Web | Desktop Application

Privacy-Preserving Updates to Anonymous and Confidential Databases Suppose Alice owns a k-anonymous database and needs to determine whether her database, when inserted with a tuple owned by Bob, is still k-anonymous. Also, suppose that access to the database is strictly controlled, because for example data are used for certain experiments that need to be maintained conﬁdential. Clearly, allowing Alice to directly read the contents of the tuple breaks the privacy of Bob (e.g., a patient’s medical record); on the other hand, the conﬁdentiality of the database managed by Alice is violated once Bob has access to the contents of the database. Thus, the problem is to check whether the database inserted with the tuple is still k-anonymous, without letting Alice and Bob know the contents of the tuple and the…

The Geometric Efficient Matching Algorithm for Firewalls

Parallel And Distributed System, Web | Desktop Application

The Geometric Efficient Matching Algorithm for Firewalls The firewall is one of the central technologies allowing high-level access control to organization networks. Packet matching in firewalls involves matching on many fields from the TCP and IP packet header. At least five fields (protocol number, source and destination IP addresses, and ports) are involved in the decision which rule applies to a given packet. With available bandwidth increasing rapidly, very efficient matching algorithms need to be deployed in modern firewalls to ensure that the firewall does not become a bottleneck Since firewalls need to filter all the traffic crossing the network perimeter, they should be able to sustain a very high throughput, or risk becoming a bottleneck. Thus, algorithms from computational geometry can be applied. In this paper we consider a…

In Cloud, Can Scientific Communities Benefit from the Economies of Scale?

Parallel And Distributed System, Web | Desktop Application

In Cloud, Can Scientific Communities Benefit from the Economies of Scale? The basic idea behind Cloud computing is that resource providers offer elastic resources to end users. In this paper, we intend to answer one key question to the success of Cloud computing: in Cloud, can small or medium-scale scientific computing communities benefit from the economies of scale? Our research contributions are three fold: first, we propose an enhanced scientific public cloud model (ESP) that encourages small or medium scale research organizations rent elastic resources from a public cloud provider; second, on a basis of the ESP model, we design and implement the Dawning Cloud system that can consolidate heterogeneous scientific workloads on a Cloud site; third, we propose an innovative emulation methodology and perform a comprehensive evaluation. We found…

A NOVEL ANTI PHISHING FRAMEWORK BASED ON VISUAL CRYPTOGRAPHY

Parallel And Distributed System, Security and Encryption, Web | Desktop Application

A NOVEL ANTI PHISHING FRAMEWORK BASED ON VISUAL CRYPTOGRAPHY Phishing is an attempt by an individual or a group to thieve personal confidential information such as passwords, credit card information etc from unsuspecting victims for identity theft, financial gain and other fraudulent activities. In this paper we have proposed a new approach named as "A Novel Anti phishing framework based on visual cryptography" to solve the problem of phishing. Here an image based authentication using Visual Cryptography (vc) is used. The use of visual cryptography is explored to preserve the privacy of image captcha by decomposing the original image captcha into two shares that are stored in separate database servers such that the original image captcha can be revealed only when both are simultaneously available; the individual sheet images do…

Balancing the Tradeoffs between Query Delay and Data Availability in MANETs.

Parallel And Distributed System, Web | Desktop Application

Balancing the Tradeoffs between Query Delay and Data Availability in MANETs. In mobile ad hoc networks (MANETs), nodes move freely and link/node failures are common, which leads to frequent network partitions. When a network partition occurs, mobile nodes in one partition are not able to access data hosted by nodes in other partitions, and hence significantly degrade the performance of data access. To deal with this problem, we apply data replication techniques. Existing data replication solutions in either wired or wireless networks aim at either reducing the query delay or improving the data availability, but not both. As both metrics are important for mobile nodes, we propose schemes to balance the tradeoffs between data availability and query delay under different system settings and requirements. Extensive simulation results show that the…

Resource-Aware Application State Monitoring.

Parallel And Distributed System

Resource-Aware Application State Monitoring. The increasing popularity of large-scale distributed applications in datacenters has led to the growing demand of distributed application state monitoring. These application state monitoring tasks often involve collecting values of various status attributes from a large number of nodes. One challenge in such large-scale application state monitoring is to organize nodes into a monitoring overlay that achieves monitoring scalability and cost-effectiveness at the same time. In this paper, we present REMO, a REsource-aware application state MOnitoring system, to address the challenge of monitoring overlay construction. REMO distinguishes itself from existing works in several key aspects. First, it jointly considers inter-task costsharing opportunities and node-level resource constraints. Furthermore, it explicitly models the per-message processing overhead which can be substantial but is often ignored by previous works. Second,…

Parallel And Distributed System, Web | Desktop Application

Cooperative Provable Data Possession for Integrity Verification in Multi-Cloud Storage. Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing. In this paper, we address the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and data migration, in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients’ data. We present a cooperative PDP (CPDP) scheme based on homomorphic verifiable response and hash index hierarchy. We prove the security of our scheme based on multi-prover zero-knowledge proof system, which can satisfy completeness, knowledge soundness, and zero-knowledge properties. In addition, we articulate performance optimization mechanisms for our scheme, and in particular present an efficient method for selecting optimal parameter values…
