sigature+verification

1. The main idea of this paper is that through Graphology and Graphometry you can identify a person's characteristics, health issues, hidden talents, moods..ect. Graphology is used in most cases to detect authenticity or forgery, where as Graphometry is used mainly to get psychic impressions about a person from a sample of their handwriting.

2. In this paper, the experiments that were performed were a series of handwriting samples (signatures) in areas of different size spaces. This would allow them to see how signatures differentiate when they are constrained. The made several forms to evaluate the signatures, and had a sample of 1,316 signatures from 94 writers (14 signatures per person). First, they asked the writer to simply sign their signature without constraints, then they were asked to sign 13 more times not respecting the constraints. They found that 89% of the writers did not change the way they signed based on the constraint, they kept it in the same scale.

3. The experiment performed for signature verification was good science because the researchers used a large sample size, including 93 people that were both informed and not informed about the experiment being performed. The test was consistant and had a single variable that resulted in the conclusion that people keep their signatures relatively consistant when provided with different scales.

4. The authors determined that forensic graphology was the study of the specific characterizations of a person's writing style. This included all the things that make up a person's signature, such as: calibre, alignment to baseline, porportion and spacing. All of these are identified when using forensic graphology. With these characteristics, anaylists can determine a signatures' uniqueness or a person's specific writing style.





5. Five interesting facts that we found in our paper were: -Handwriting has been being studied for almost 400 years. -The first person to carry out systematic observations in handwriting was Camillo Baldi. -The word "Graphology" comes from the Greek words //graphein// and //logos//. -Graphology is said to be useful for discovering everything, from heath issues, past experiences, hidden talents, and morality. -They plan to used Graphology for automatic signature verification.
