Anonymous letters have been an integral part of our society since time immemorial, so finding their authors is a constant headache for employees of security units of state and non-state structures. The purpose of anonymous letters can be different: it can be a threat of a terrorist act, a leak of compromising information and, finally, a trivial extortion of certain sums of money.
In order to collect alarm information about anonymous texts to your address, it is necessary to have a special system for reporting these facts. For as the ancients said: He who is warned is armed. Facts of malicious fabrications or partial relatively accurate information about you and your business should not catch you unawares. Therefore, as the great Dale Carnegie bequeathed, make friends and connections in all controlling, etc., etc. bodies.
By the way, according to a statement in the media by a senior tax police officer, one of the most effective ways to identify persistent tax defaulters are anonymous letters, the authors of which in most cases are deceived wives and abandoned mistresses of businessmen.
Naturally, at the very first stage of detecting the fact of sending anonymous emails about you and your business it is necessary to carefully analyze to what extent the facts stated in the document can be confirmed by documents or testimonies, and to provide a plan of actions to neutralize possible consequences.
If you receive information about the distribution of anonymous letters against you or your business, it is necessary to investigate the original letter (hereinafter the document), it is also desirable to get the cover in which it came (an envelope or something similar). Having the original and not a copy is very important for further investigation for many reasons.
Possible algorithm for investigating available anonymous text.
Investigation of the method of document distribution and delivery: Postage, courier delivery, posting as advertisements, covert delivery associated with infiltration of the protected object. Examination of the envelope in a postal shipment. place of dispatch, date of dispatch, presence of post office stamps, individual characteristics of the envelope. Examination of the document carrier material: how it corresponds to the one available in your office; what distinctive features it has; how scarce the carrier material is and where similar material can be found. Method of putting information on the document: handwritten, made up of pasted letters of newspapers and magazines, typewriter, computer printer, individual characteristics of the technique of putting information on the medium. 5. psycho-graphological expertise solves the questions of correlation between the handwriting of an object and the features of its character, mental state and behavioural characteristics. This type of expertise makes it possible to diagnose the object under study by performing an expert assessment of all its characteristic personality traits based on the sample of its handwriting.
Unfortunately, this type of examination in real conditions is not applicable, because it requires involvement of experts of very high qualification. A similar study with the help of computer techniques is difficult because of the high cost of this software.
6. Morphological and content analysis occupy a special place among information processing methods. And they are both so simple and versatile that they are successfully used by both intelligence analysts and commercial experts. Even a small firm without significant material and intellectual resources is able to conduct such research and obtain certain results.
Content analysis is concerned with the study of the semantic content of a text, morphological its external form. When they are used together, they make it possible to draw a fairly complete psychological portrait of the author of an anonymous text. These methods are also suitable for investigating the spoken speech of the subject of operational interest.
Basically, these techniques are based on several psychological principles.
1. Each person is strictly individual and, therefore, when creating a text, he or she is bound to add something personal to it, i.e. information about himself or herself. The task is to decipher correctly what is hidden between the lines. Any text necessarily carries information about its author, about his life credo, experience, professional and general educational level.
2. It is also clear enough that any text reflects the author’s current state of mind and emotions. Think of yourself while writing something, and you will immediately realize that everyone projects themselves onto what they are writing.
Unfortunately, it is quite difficult to identify texts written in formalized formal language. The closer the text is to the stereotype, the harder it is to understand the essence of its author. Conversely, the more the text departs from the template, the more different information about its author can be obtained.
I want to emphasize that this article will give you only the general principles of the analysis. Besides you should take into consideration the fact, that any assumptions are always of a probabilistic nature; therefore you should not make global conclusions and try to make mathematically correct and far-reaching forecasts.
As I said before, content analysis is one of the most effective means of evaluating text. This technique has a long history. The first mention of its application in practice dates back to the eighteenth century. At that time the church, counting the frequency of occurrence of Christ-related topics, made a decision about the heretic character of this or that book, and, consequently, about the godliness of this or that author. That is, from the beginning, it was the repressive apparatus that was its most ardent adherents.
In recent history, the most striking example of the use of content analysis is the work of American military censorship during World War II. The basis for accusing media editors of having links to the Nazis was the detection of similarities in the repetition of certain themes in the pages of certain publications.
As a method of quantitative study of information content to discover facts of interest in it, content analysis is rigorous, systematic and, most importantly, focused on quantitative indicators. The goal of the method is to calculate how certain semantic units are represented in the available body of information.
