Nw-a day student attendance tracking systems emplyed in universities require a lt f human interventin. Als its strage fr future uses a lt f memry. Peple can use their mbile gadgets and ther devices like tabs, laptps, ipad etc. fr using these services. These services prve t be f great use in fields like educatin (e.g. prviding educatinal resurce strage and databases, s, educatinal applicatins and tls fr students and teachers and clients lcated within the cllege campus invlving in an educatinal prgram). Cnsidering the present cmmunicatin system, the prpsed system prvides a cst effective applicatin fr users in their daily life. The clud based intra cllege cmmunicatin system using mbile clients (CICCSM) can raise the quality f educatin system t a new level [2]. Keywrds: Attendance Tracking using Bluetth, Ntificatin, Cmmunicatin, Ntes sharing. I. INTRODUCTION This paper puts frward the design methd f netwrk chat system based n clud cmputing technlgy. Tday's netwrk times, "Netwrk" this wrd already thrugh ppular feeling, the develpment f cmputer netwrk speed is amazing, it greatly reduces the human distance, and it apparently expanded the cmputer functins. And as ne f netwrk applicatin chatting tls, it is als mre and mre attentin by peple and welcme, a gd netwrk chat tl can make any distance cmmunicatin cnvenient and quick. In fact, in mdern scial netwrk chat sftware develpment has quite mature, all kinds f cmplete functin and friendly interface f sftware is quite beautiful. The clud supprts server-based applicatins and data services t the user which display the utput n the client device. If the user wants t create a dcument using a wrd prcessr, fr example, the clud gives a suitable applicatin running n the server which displays wrk dne by the user n the client web brwser display. The memry allcated t the client's wrkstatin fr web brwser is used t make the applicatin data appear n the client system display, but all changes and cmputatins are recrded by the server system, and final results including files created r altered are permanently stred n the clud servers. The perfrmance f the clud applicatin is dependent upn the netwrk access, reliability and speed as well as the prcessing speed f the client device. Private cmpany, such as their emplyer. The clud cmputing wrks n a client-server architecture using web brwser prtcls. 2015, IJARCSMS All Rights Reserved 43 P age

2 Internatinal Jurnal f Advance Research in Cmputer Science and Management Studies Vlume 3, Issue 2, February 2015 pg Clud Based Intra Cllege infrmatin cmmunicatin system using mbile clients, we are using sftware as a services (SaaS architecture). we need t implement web service fr intra cllege cmmunicatin. The cmmunicatin will ccur between nn-teaching staff, teaching staff and students. The nn teaching staff and teaching staff use pc s and students use mbile phnes fr the cmmunicatin. 1.1) Clud Cmputing Clud calculative fundamental is, thrugh the analysis f the distributin f the distributed cmputer, rather than the lcal cmputer r the remte server, the peratin f the enterprise data center will be mre similar as Internet. This makes the enterprise can will resurce switch n the applicatin f need, accrding t demand access t the cmputer and strage system. This is a kind f revlutinary act, fr example, this is just like is the ld single generatr mdel turned t the pwer plant t centralized pwer supply mde. It means cmputatinal ability t als can serve as a kind f gds circulatin, as gas, water and electricity, take with cnvenient, fare is lw. The biggest different depend n, it is thrugh the Internet fr transmissin[2]. Clud cmputing has the blueprint f be vividly prtrayed: in the future, nly need a laptp r a mbile phne, yu can realize ur need thrugh netwrk service everything, even including supercmputing such task. Frm this perspective, the end user is the clud calculative true wner. Clud cmputing applicatins include such a new idea r new cncept: the pwer f the wrld tgether, t give which every member f the using, Figure 1. Clud strage f clud cmputing At present, the PC is still ur daily life f the cre tls-we use PC dcuments, strage material, thrugh r U plate and share infrmatin. If PC hard disk is brken, we will because material lss and stranded. And in "clud cmputing" era (nte: the fllwing "clud cmputing" are referred t as the "clud"), "clud" will be dne fr us strage and cmputing wrk, "clud" is cmputer grup, and each grup includes the thusands f Taiwan, r even millins f cmputer. "Clud" benefits are that ne f the cmputers can update, guarantee "clud" frever. 1.2) Security Using Cryptgraphic Hash Functin Cryptgraphic hash functin is a hash functin, that is, an algrithm that takes an arbitrary blck f data and returns a fixed-size it string, the (cryptgraphic) hash value, such that an (accidental r intentinal) change t the data will (with very high prbability) change the hash value. The data t be encded is ften called the message, and the hash value is smetimes called the message digest r simply digest[6]. The ideal cryptgraphic hash functin has fur main r significant prperties: 1. It is easy t cmpute the hash value fr any given message. 2. It is infeasible t generate a message that has a given hash. 2015, IJARCSMS All Rights Reserved ISSN: (Online) 44 P age

It is infeasible t find tw different messages with the same hash. Cryptgraphic hash functins have many infrmatin security applicatins, ntably in digital signatures, message authenticatin cdes (MACs), and ther frms f authenticatin. They can als be used as rdinary hash functins, t index data in hash tables, fr fingerprinting, t detect duplicate data r uniquely identify files, and as checksums t detect accidental data crruptin. Indeed, in infrmatin security cntexts, cryptgraphic hash values are smetimes called (digital)fingerprints, checksums, r just hash values, even thugh all these terms stand fr functins with rather different prperties and purpses. The Secure Hash Algrithm is ne f a number f cryptgraphic hash functins published by the Natinal Institute f Standards and Technlgy (NIST) as a U.S. Federal Infrmatin Prcessing Standard (FIPS). What is the Secure Hash Algrithm (SHA and SHA-1)? The Secure Hash Algrithm (SHA), the algrithm specified in the Secure Hash Standard (SHS), was develped by NIST and published as a federal infrmatin prcessing standard (FIPS PUB 180). SHA-1 was a revisin t SHA that was published in The revisin crrected an unpublished flaw in SHA. Its design is very similar t the MD4 family f hash functins develped by Rivest The algrithm takes a message f less than 264 bits in length and prduces a 160- bit message digest. The algrithm is slightly slwer than MD5 (but the larger message digest makes it mre secure against brute-frce cllisin and inversin attacks Verifying the integrity f files r messages. An imprtant applicatin f secure hashes is verificatin f message integrity. Determining whether any changes have been made t a message (r a file), fr example, can be accmplished by cmparing message digests calculated befre, and after, transmissin (r any ther event). Fr this reasn, mst digital signature algrithms nly cnfirm the authenticity f a hashed digest f the message t be signed. Verifying the authenticity f a hashed digest f the message is cnsidered prf that the message itself is authentic Passwrd verificatin. A related applicatin is passwrd verificatin. Passwrds are usually nt stred Jurnals are gverned by an Intellectual bdy and they select the mst suitable paper fr publishing after a thrugh analysis f submitted paper. elected paper get published (nline and printed) in their peridicals and get indexed by number f surces. 1.3) Bluetth Attendance The current student attendance tracking systems require a lt f human interventin cnsuming, a lt f paper wrk and time. Existing methdlgy requires manual tracking and then duplicating it t SQL databases. This can be replaced by autmating the prcess. A wireless tracking system t mnitr individual student present[3] inside the campus will save a lt f time. Any students can keep track f their individual attendance and take actins accrdingly. The prfessrs can track his class attendance r individual students recrd with very less time[3]. Fig. 1.3 Basic Infrastructure f Bluetth Attendance [4] II.

User can cmmunicate using Persnal cmputers and laptps. Availability f internet cnnectin is the mst imprtant factr fr the users. Fr eg tw peple chatting n gmail require t be having internet cnnectin. The cst f using internet is pretty high and nt affrdable fr every user. Due t high netwrk traffic perfrmance can degrade. Security is majr cncern. Hackers and illicit users can btain passwrd and ther imprtant infrmatin. Clud based intra cllege infrmatin cmmunicatin system using mbile clients : T vercme the disadvantages f the current system we have prpsed the CICCMC. The system uses wi-fi technlgy which is the majr advantage. The system prvides high availability. Any user can use the services by turning n the wi-fi f its system. The users need nt be lgin at the same time fr cmmunicatin. a user can send mail t his friend. The friend can see the mail when he lgins. Incase f chat sessin ne user lgs ff then the messages sent by the ther persn will be autmatically stred in messages. We are find all papers related t this intra system and check and find what drawbacks r what prblems that system face and finally cllect all prblems which are presented in fllwing tables. III.

Fig. 3. Sketch f Clud Based Intra Cllege Infrmatin Cmmunicatin System Using Mbile Client. IV. FEATURES After the develpment, analyzes the efficiency f a range query ver the data that is encrypted by EOB where the prpsed OB is used. The main fcus was t analyze the searching efficiency in terms f the false psitive rate. T d this, the prbability distributin f the rate f the width f a bucket t the size f the plaintext space was first analyzed t shw that the width f a bucket is nt skewed t be extremely large r small. This even-bucket-width prperty gives the prpsed scheme a gd querying perfrmance n average. In the prpsed OB, the p _ 1 pints are randmly unifrmly sampled in the plaintext space [0, M -1].The width f the ith bucket was determined by the selected pints f (i-1) th rder and i th rder because the width is the difference f these tw pints. Therefre, t analyze the width f a bucket, it is imprtant t analyze the prbability distributin f the psitin f the selected pints.» Manage ntes: The staff members can uplad ntes f their respective subjects fr the students. Students can uplad their wn ntes t circulate them amng their classmates. The user can mdify, add, and delete mtes accrding t their requirements. This service has medium pririty as it will be used n average basis by the users.» Assign task: The HOD can assign the daily task t its department staff and manage it. Similarly teachers can assign their prject task and subject assignments t students.» Message/SMS: Fr cmmunicatin in real time the system prvides SMS service. The devices within wi-fi range can use the service free f cst as cmpared t the service prvider SMS services which are charged.» service can be used by the users t mail and transfer infrmatin. 2015, IJARCSMS All Rights Reserved ISSN: (Online) 47 Page
