Digital forensics: A technological revolution in forensic sciences.

Computer Forensics World is a growing community of professionals involved in the digital forensics industry. It is an open resource, free for all to access and to use. Digital investigations and crime regularly cross international and language borders today. Open database connectivity technology is now providing access to a wide range of database technologies, such as neural networks and pattern recognition databases, which are being used to analyze shoe prints and tool marks. These new computer-aided analysis tools can link and chart case information, allowing the investigator to question the data and pose scenarios as well as suggest and follow possible investigative paths. As a result, connections that often took weeks or months to come to light are revealed in a fraction of the time. Forensics is just beginning to get looked at, but the problems are cost and government is slow to adopt new technology. In this paper we discussed about the kingdom of Digital Forensics and Computer Forensic World. The study consists of Computer Forensic World, Digital Forensics (MEK, AFF, and Keyword Search etc.), and the Future Forensics Labs.

Significance of sacral index in estimation of sex in sacra of cadavers in Punjab.

In the identification of sex in human skeletal remains, Sacrum is an important bone for identification of sex in human skeletal system. Since it is a component of axial skeleton and because of its contribution to the pelvic girdle and in turn to the functional differences in the region between the sexes, it has an applied importance in determining sex with the help of measurements carried upon it. Over the years different authors had carried various types of measurements on human sacra of different races and regions. A study for sexing of sacra was carried on 40 sacra (20 male & 20 female sacra) in Punjab. The method used was sacral index. The measuring instrument used was sliding vernier calliper. All the sacra taken were normal. The sacral index of sacra its mean and standard deviations were calculated. Then calculated range (mean ± 3S.D.) and demarking points (DP) of both the parameters and the percentage of bones in which sex could be identified by them was also calculated. The results were compared with the available literature. It was found that D.P of sacral index was very reliable in sexing of sacra.

Significance of weight and maximum length as an objective for sexing of unknown femora a research study in Punjab.

Identification of sex from the skeleton is an important demographic assessment in medico legal investigations. Length and weight of femur are the two reliable skeletal elements for sex determination. Large number of reports does exist about the sex determination from long bones such as femur anthropological and forensic contexts. It is a very well known factor that skeletal dimensions and standards of skeletal identification do vary with different populations. The present study aims at obtaining results from two femoral dimensions in Punjab cadavers to develop standards in determination of sex. In case of femur maximum length and weight are one of the parameters significantly important in sex dimorphism. The matter being of medico legal importance, an attempt was made by forensic experts and anatomists of SGRDIMSAR, Sri Amritsar to carry out various measurements to differentiate the sex of the femora. This was done in femora of either known sex. The diseased femora were rejected. The aim of this study is to prove that the weight and the Maximum length of femur will significantly differentiate the sex of the femora and this fact will help to arrive at an objective process for the sexing of femora of unknown sex.
