my brother, this issue has come up before. it is one of the ways by which people try to increase their chances of winning. (to enter into the draw more than once - that is changing the positions of their names). cant say much about that but just want to draw your attention to that.
I think he is right. i have read what sammy said somewhere here
i do not want to prolong this topic. the post you referring to was posted by sammy as De don by then. He did not give any prove then and have not given any prove today. there is facial recognition software been used by KCC to disqualify multiple entries before and during the draw. Note that name is not the only identification tool available but also photo.
2004:Combating Visa Fraud
In November 2004, the Department established a fraud prevention unit at the Kentucky Consular Center to counter fraud in the Diversity Visa lottery program and with petition-based visas, such as temporary workers. The consular center provided background to support six formal fraud investigations and has returned 166 non-immigrant visa petitions to the Department of Homeland Security for revocation based on fraud indicators. The consular center continues to employ facial recognition technology as a tool against visa fraud, especially in the lottery program. In 2005, more than 7.5% of winning entries were disqualified as duplicate entries using facial recognition. Over 100,000 more duplicate entries were eliminated using facial recognition and “matching technologies” before the winners were selected.
KCC has made several improvements to its processing of the DV lottery entries to detect multiple entries and to screen cases for possible fraud indicators before they are sent to consular posts for adjudication. KCC piloted facial recognition software in 2001 and, in 2003, moved to an electronic application process, known as e-DV. Both facial recognition and e-DV improve KCC’s ability to detect multiple entries and to detect possible fraud indicators. Prior to this, the DV lottery was paper-based, which made it difficult for KCC employees to catch multiple entries. Now, all e-DV entries go through electronic and manual procedures to screen out ineligible entries. The entries are screened electronically for exact duplicate digital photographs or biographic information; exact duplicates are disqualified. Next, all principal applicant entries selected in the lottery are checked with facial recognition software against galleries (by region and by gender) drawn from the entire e-DV database to further eliminate duplicate entries based on photo matches. Possible matches are returned to KCC’s facial recognition technicians, who then make a determination on whether or not a valid match exists. KCC reported that it detected 7,622 multiple entries in 2005, 7,166 in 2006, and 3,969 in 2007. KCC’s fraud prevention manager attributed the decreasing number to the success of facial recognition software, suggesting that applicants and visa industry consultants were not submitting as many multiple entries because they had learned that KCC would detect and disqualify them
If KCC’s facial recognition technicians detect multiple entries before the entrant has been notified of being selected in the lottery, KCC will disqualify the entry and not notify the entrant of the disqualification. In the past, KCC disqualified the entrant and sent a disqualification letter to the entrant regardless of whether the entrant had already been sent a notification letter. Consular Affairs’ legal department requested KCC to cease disqualification of entrants who had already been notified as this could be perceived as an adjudicatory decision by KCC.36 KCC now forwards the information on the facial recognition match to the post so the consular officer can make the decision.
In addition to facial recognition software, KCC employees search for other fraud indicators as they collect additional documents from individuals selected in the lottery and prepare to send their cases to posts for adjudication. For example, they note, through “fraud flags,” if applicants (1) added a spouse or children to their case after being selected in the lottery, (2) if there were substantial changes to biographic details, or (3) if the applicant appeared in a different entry with different family members. In their scan of applicants selected in the 2005 DV program, KCC employees found 804 “pop-up” spouses or children; applicants from Ghana, Nigeria, and Ukraine had more “pop-ups” than any other country. KCC’s fraud flags are noted in both the electronic and hard copy files that are sent to posts, and several of the consular officers at the posts we reviewed said that the fraud flags were useful for their adjudication of DV cases. With the advent of e-DV it also became possible to provide an electronic comparison of the applicant’s lottery entry photograph to the photograph submitted with the visa application so that consular officers can review and compare these photographs. This process has assisted numerous posts in identification of imposters. Finally, in 2004, KCC hired a full-time fraud prevention manager, who oversees fraud prevention programs for both the DV program and petition-based nonimmigrant visa programs, which are also processed at the KCC. In commenting on this report, State mentioned some additional tools it uses to prevent DV fraud, such as fraud conferences and fraud prevention management training, which include DV patterns and issues.
