Online Crime Investigation
ABSTRACT
Crime
investigation system keeps track and maintains history about each and every
case in the database which ultimately avoids manual and paper work. It is based
on decentralized client-server architecture in order to facilitate independent
functioning of all units. Here information flows from lower units to higher
units and vice-versa.
The
project is built on multi-tier architecture. It provides quick access to data
which is essential for effective prevention, control and detection of crime. It
also helps decision-making and decision support processes.
Crime
investigation system is an intelligent decision support system that can assist
human investigators by automatically constructing plausible scenarios.
Some of the benefits of crime
investigation system to existing system are quick retrieval of data, huge
saving of time, proper deployment & utilization of manpower, cost reduction
leading to saving in expenditure
It
enables the police service to supervise and administer any incident and process
related information by providing standardized processes and procedures to
monitor and improve performance.
Using
this application people can give their complaint through online. To register
any type of complaint they need to register his personal details along with
login details. Once he/she registers in the application he/she can post their
complaints.
Identification of need:
The
first step of the system analysis process involves the identification of need.
The success of a system depends on how accurately a problem is defined,. User
need identification and analysis are concerned with what the user needs rather.
The analyst think about solutions and whether the problem is worth solving.
This step is intended to help the user and the analyst understands the real
problem rather than its symptoms.
In
the existing system, the objectives of the problem situation must be understood
within the framework of the organization under the system planning. If
objectives are misunderstood it is easy to solve the wrong problem. In the
present system, for computing environments that are connected via networks,
ORACLE combines the data physically located in different computers into one
logical database that can be accessed by all network users.
Distributed
systems, have the same degree of user transparency and data consistency as
non-distributed systems; yet receive the advantage of local database
management. Hence it has been suggested that an RDBMS application is preferred.
The proposed system is to meet the enterprise wide system and software
requirements for designing and developing custom solutions.
Preliminary Investigation:
The
first step in the system development life cycle is the identification of a
need. This is a user’s request to change, improve or enhance an existing
system. Because there is likely to be a stream of such requests, standard
procedures have been established to deal with them. The preliminary
investigation is one way of handling this. The objective is to determine
whether the request is valid and feasible before a recommendation is reached to
do nothing, e.
The user request identifies the need for
change and authorizes the preliminary investigation. It may undergo several
modifications before it becomes written commitment. Once the request is
accessed to, the following activities are carried out: background
investigation, fact-finding and analysis, and presentation of results- called
project proposal.
Existing System:
The
existing system is a manual process. Numerous accounts are to be maintained: 1)
Complaint Details. 2) Maintain Thieves Information 3) Forward Thieves
information to all departments manually and 4) Maintain Employee Details. The
existing system to be maintains lot of paper information’s. When any
statistical analysis is to be carried out, for example: a comparison of the
past year’s performance with that of the current year, it is also a laborious
task of referring to many record books, compiling lists, and carrying out the
analysis work.
Problems with Existing System:
Ø Lot of space is required to store all the
details of the thieves and the complaints
Ø Data is spread across a number of record
books, which have to be manually integrated to arrive at a solution.
Ø The system is prone to human errors.
Detection of errors is a difficult task since everything is done manually.
Ø Tracking of errors to their origin is
difficult
Ø There is no security to data. Anyone can view
through the data concerning the activities of the Consultancy
Ø Any modification to the data requires
searching through all the records and then making the relevant changes.
Ø The process is very time consuming.
Proposed System:
Manual
processing of data is very tedious and time consuming and leads to erroneous
results, at times. In order to overcome
these snags computers are being used extensively in all fields thereby
minimizing manual labor and errors to a great extent.
Taking all the advantages involved in
computerizing, the proposed system “Online Crime Report” integrates all the
manual activities by linking them under a single head. This System processes
the day-to-day activities and generates tender reports that help the user to
get a good grasp of the situation(s) and take decisions quickly and in-time.
Purpose of
the system
The
main purpose of the system is to design and implement an effective intelligent
system to register client details and post complaints to concerned departments.
The main client requires the system to be effective and must be capable of
registering the complaint and is provide security
