Computer Forensics

The proliferation of computer use in today's networked society is creating some complex side effects in the application of the age-old greed, jealousy, and revenge. Criminals are becoming much more sophisticated in committing crimes. Computers are being encountered in almost every type of criminal activity. Gangs use computers to clone mobile telephones and to re-encode credit cards. Drug dealers use computers to store their transaction ledgers. Child pornography distributors use the Internet to peddle and trade their wares.

Fraud schemes have been advertised on the Internet. Counterfeiters and forgers use computers to make passable copies of paper currency or counterfeit cashiers checks, and to create realistic looking false identification.In addition, information stored in computers has become the target of criminal activity. Information such as social security and credit card numbers, intellectual property, proprietary information, contract information, classified documents, etc., have been targeted. Further, the threat of malicious destruction of software, employee sabotage, identity theft, blackmail, sexual harassment, and commercial and government espionage is on the rise.

Personnel problems are manifesting themselves in the automated environment with inappropriate or unauthorized use complaints resulting in lawsuits against employers as well as loss of proprietary information costing millions of dollars. All of this has led to an explosion in the number and complexity of computers and computer systems encountered in the course of criminal or internal investigations and the subsequent seizure of computer systems and stored electronic communications.

Computer evidence has become a 'fact of life' for essentially all law enforcement agencies and many are just beginning to explore their options in dealing with this new venue. Almost overnight, personal computers have changed the way the world does business. They have also changed the world's view of evidence because computers are used more and more as tools in the commission of 'traditional' crimes. Evidence relative to embezzlement, theft, extortion and even murder has been discovered on personal computers. This new technology twist in crime patterns has brought computer evidence to the forefront in law enforcement circles

please gv me complete report on the topic COMPUTER FORENSIC and 3D-OPTICAL DATA STORAGE TECHNOLOGY

Computer forensics is a forensic science pertaining to legal evidence found in computers and digital storage mediums. Computer forensics is also known as digital forensics.computer forensics is to explain the current state of a digital artifact. The term digital artifact can include a computer system, a storage medium (such as a hard disk or CD-ROM),electronic document (e.g. an email message or JPEG image) or even a sequence of packets moving over a computer network. The explanation can be as straightforward as "what information is here?" and as detailed as "what is the sequence of events responsible for the present situation?" computer forensics also has sub branches within it such as firewall forensics, network forensics, database forensics and mobile device forensics.many reasons to employ the techniques of computer forensics:
In legal cases, computer forensic techniques are frequently used to analyze computer systems belonging to defendants (in criminal cases) or litigants (in civil cases).
To recover data in the event of a hardware or software failure.
To analyze a computer system after a break-in, for example, to determine how the attacker gained access and what the attacker did.
To gather evidence against an employee that an organization wishes to terminate.
To gain information about how computer systems work for the purpose of debugging, performance optimization, or reverse-engineering.Special measures should be taken when conducting a forensic investigation if it is desired for the results to be used in a court of law. One of the most important measures is to assure that the evidence has been accurately collected and that there is a clear chain of custody from the scene of the crime to the investigator-and ultimately to the court. In order to comply with the need to maintain the integrity of digital evidence, British examiners comply with the Association of Chief Police Officers (A.C.P.O.) .
These are made up of four principles as follows:-

Principle 1: No action taken by law enforcement agencies or their agents should change data held on a computer or storage media which may subsequently be relied upon in court.

Principle 2: In exceptional circumstances, where a person finds it necessary to access original data held on a computer or on storage media, that person must be competent to do so and be able to give evidence explaining the relevance and the implications of their actions.

Principle 3: An audit trail or other record of all processes applied to computer based electronic evidence should be created and preserved. An independent third party should be able to examine those processes and achieve the same result.

Principle 4: The person in charge of the investigation (the case officer) has overall responsibility for ensuring that the law and these principles are adhered to.
