The Dangers of the Online World

Not only is there now a greater general awareness of the capabilities of digital evidence and its potential within legal cases, additionally, reports of websites containing indecent images of children are also continually rising each year. Increasing resources are now being spent on examining data of this type as part of legal cases where previously it was thought unnecessary. We now frequently encounter cases involving supportive evidence (such as user and/or Internet history) as well as the basic evidence that is relied upon as part of the Prosecution case. However, it seems inevitable that an increase in the number of cases limits what can be achieved within a Police Force's Hi-Tech Crime Unit. Consequently, that question is normally answered until well after the case has been initiated. Identifying the basic origins of a file is normally relatively straightforward. For instance, the location of the file normally provides the biggest clue; the activity surrounding its creation is another indicator. Identifying the basic origins of a file is normally relatively straightforward.

 When dealing with cases involving indecent images of children, for instance, there are various methods for an image to have been created on a computer hard drive, including, but not limited to, websites accessed whilst browsing the Internet, received e-mails and peer-to-peer software, such as KaZa. The images had been stored in two folders within his 'user' profile on the family's home computer. The Prosecution relied upon the fact that the unlawful images were contained within manually created folders of the Defendant's 'user' profile and they also identified the presence of keyword searches for terms that were likely to result in the creation of unlawful material. I examined the case and noted that the 9 static images had arrived via a small number of web pages containing legitimate adult pornography and had been created automatically by image downloading software. This case is not an exception. In approximately 20% of the cases in which we are involved we have been responsible for identifying crucial new evidence that has caused the case to be withdrawn. For the Police, an examination of this detail is irrelevant for the majority of cases. Cases involving files encountered and downloaded via websites are also frequent areas of misunderstanding. The presence of a web page or file on a hard drive can be the result of intentional user access, or alternatively, the operation of one of a number of different scripts and software. These scripts can cause the user's Internet browser to be automatically forwarded to web pages containing certain material or cause certain files to be added to the hard drive without the user's knowledge. As digital media increases in capacity it allows users to store more data but also increases the possibility of software or anomalous mechanisms causing the creation and movement of files. computer science masters degree, computer science London, computer science PHD, computer science degree salary, department of computer science, computer science B.SC, computer science final year project, final year project computer science, about computer science, jobs computer science, school of computer science, computer science news, computer science university ranking UK, computer science studies, computer scientist, B.SC in computer science, computer science quotes, computer science rankings, computer science project, Columbia computer science, UCLA computer science, computer science unplugged, Cornell computer science, computers science, computer science salary, computer science colleges, computer science project topics, best universities for computer science, theoretical computer science, computer science CV, computer science quotes, computer science rankings, computer science project, Columbia, computer science, UCLA computer science, computer science unplugged, Cornell computer science, computers science
