Evidence Integrity is the backbone of any digital forensic process and no doubt, information stored in logs is treasured sources of such evidence in forensic examination. Given the significance of maintaining audit trails and log information in aiding the proving and or disproving facts in any litigation, a digital forensic perspective underscores the need to secure and preserve adequately evidentiary log information for the purpose of admissibility. It should be understood that the admissibility of evidence solely depends on the reliability and wholeness of such evidence which defines its integrity. This theory ensures that evidence acquired during investigation is not tampered with or compromised consciously or unconsciously either by human actions, inactions, adoptive procedures or as a result of the tools used. Leaning on an understanding of existing integrity models and approaches, our work employs a suiting abstract digital forensic model for the development of ‘Log integrity’; a log-centered evidence preservation framework. The methodology adopts a three-phased integrity application technique that explored integrations with Clark-Wilson’s Integrity model and Casey’s Certainty Scale; all for assuring the integrity of log information as forensic evidence. We also elaborate on a validation approach explored using a test scenario which satisfactorily and within the scope of the study yields estimable results in terms of integrity preservation enhancement of log files. Therefore, besides the secure acquisition of digital evidence of great importance also is the task of ensuring that the integrity of such evidence is not compromised at any stage of the investigation.

The present time has been marked by various types of crime and although little media coverage, the fraud has done grow the statistical data, much to blame for the social situation that the country is experiencing. Thus, the courts are filled with cases involving the forgery and counterfeiting of documents, which is an issue that only an expert in analysis of documents may be able to solve. At European level, Portugal remains at the top of the list in relation to fraudulent documents, followed by Italy and Spain. Concerning to the forensic expertise requested to the Laboratory of Scientific Police of Judicial Police in 2013 amounted to 34,425 applications which represents 13.9% of total handwriting. This country has few human resources to answer to the many request in which, sometimes could take up to 15 months. From a master study about Forgery and Counterfeiting documents, this presentation intends to do a panoramic vision about socio-demographic characteristics of offenders in Portugal such as age, sex, location, nationality, marital status, educational attainment and data relating to the process the number of expert requested by the courts, the time elapses from the request until the delivery of the expert report, punishment and the type of documents that were the subject of forensic analysis
