It is not new that technology optimizes processes and facilitates the search for results in a matter of minutes. Currently, the facial recognition It is a resource used to identify s, bring more security, as well as promote improved control of people flows in a company. 23391z
However, as we well know, technological advances are constant and nowadays it is even possible to reconstruct a face digitally with the help of DNA. Without a doubt, a great technological success, but it cannot be seen as the main tool for making serious decisions. Understand more about the case in the topics below.
The Maria Jane Weidhofer case 4b664c
Maria Jane Weidhofer was a young American woman who used to express herself artistically and experiment with textile design. She maintained a healthy lifestyle and enjoyed running and hiking in the hills of East bay. The trail Nimitz Way It was very popular and gained his favor. However, unfortunately, it was in that location where her body was found.
Weidhofer was sexually assaulted and killed in 1990 in Tilden Regional Park, California. The authorities investigating the case managed to remove the attacker's DNA to add to the case's evidence. Despite interviewing several suspects, none of them were identified and there were no arrests, and the case was closed without a solution.
However, a twist in this story occurred in 2017 when detectives from the East Bay Regional Park decided to enlist the help of the company Parabon NanoLabs, known for its services focused on DNA phenotyping, to try to find the suspect. Thus, they could recreate the criminal's face based on DNA collected at the time of the crime.
Software creates 3D model of the face from DNA 3z2x4b
A Parabon NanoLabs is a major technology company seen as a pioneer in the field of DNA-based nanotechnology. Among the main services it offers is Snapshot® Advanced DNA Analysis, the solution that was used to create a three-dimensional representation of the suspect in the Maria Jane Weidhofer case based on the genetic data collected from the criminal.
A DNA phenotyping helps generate new clues regarding a given individual, from physical appearance characteristics to pertinent information about the 's ancestry. Thus, it was discovered that he was a man with brown hair and eyes, fair skin, thick eyebrows and a face without freckles.
Due to the description given by one of the witnesses interviewed to resolve the case, a forensic professional added, through the Adobe Photoshop, a mustache on the identified face. Later, the suspect's predicted face was published by the department and generated quite a controversy at the time. However, more controversies would come with the addition of a with of facial recognition in solving the case.
Use of software by police officers generates controversy 25a40
In general, the case of Maria Jane Weidhofer gained repercussions once again because of a controversial solution made by detectives from the East Bay department. After all, they drew conclusions about the crime based on a face generated by algorithms and which was later submitted to facial recognition software. However, the use of the 3D generated model for this purpose goes against the of service of the company Parabon NanoLabs.
Facial recognition, despite the numerous benefits it brings, has the possibility of unreliable information, which can increase the likelihood of providing incorrect information to authorities. This unethical conduct, mainly disapproved by Parabon NanoLabs itself, gained increasing popularity this month through the sharing of hacked police records from Distributed Denial of Secrets.
In any case, police departments see DNA phenotyping as an additional tool that should not be the main factor for this type of decision-making, and should be one of the last solutions that a professional in the field should resort to when they no longer find clues about the case. Additionally, the accuracy of face predictions may not be accurate as the methods used by the company have not been peer-reviewed.
Until 2015, Parabon NanoLabs did not have clauses in its contracts that prohibited customers from using such facial recognition predictions for this purpose. That said, in 2016 they added the information that customers are prohibited from using facial recognition in their instant phenotype reports.
Facial recognition, DNA and new identification technologies 346lx
Although the search for Maria Jane Weidhofer's suspect generated a lot of controversy and revealed unethical conduct by authorities in the East Bay department, Brazilian NGOs use new technologies such as facial recognition to reduce the number of missing people in Brazilian territory and have presented very significant results .
The idea is to use facial recognition applications in a beneficial way and cross-reference information with DNA tests collected from emerging companies that provide the service of tracking global genealogy. It was through this mechanism that the São Paulo NGO Mothers of the Cathedral solved most of its cases.
Unlike Snapshot® Advanced DNA Analysis, the method aims to calculate the distance between 27 points on the 's face and generate a relevant result with the help of the application Family Faces, a partnership between Multiconnect to Olos technology Microsoft.
Social networks such as Facebook and Instagram are very useful in offering relevant information regarding the structure of the missing person's face. In addition to this, the resolution of these cases also occurs with the help of an ancestry DNA test kit, if the disappearance is long enough to generate no data about it on the web.
Facial recognition as a tool against crime 1xr60
Investment in facial recognition in Brazil is growing when it comes to identifying fugitives and criminal suspects. City halls in several cities have already invested in facial recognition cameras. In Bahia, for example, 1.183 arrests were made with the of this technology.
However, it is necessary to that this solution, just like what happened in the Maria Jane Weidhofer case, should not replace the investigation completely. Whereas this is just one aid among the structured and recurring processes in a police department.
Therefore, it is interesting that authorities always keep data updated and improve the use of this tool to avoid injustice and be increasingly judicious and assertive in resolving their cases.
The Maria Jane Weidhofer case and the mistakes of the East Bay team show the importance of good implementation between human beings and technology. After all, facial recognition is just one of the examples of tools that optimize the flow of activities and that should not replace human capacity and touch in decision-making.
