Voice deepfakes can't be detected by humans or security systems. Attacks on the rise

Spreading alarm messages or disclosing confidential company or bank data. Artificial intelligence is developing rapidly and almost anyone can create deepfake voice recordings at home and in high quality. Neither humans nor biometric systems can reliably distinguish artificial speech from real speech. Researchers from FIT BUT together with commercial system developers now want to design more reliable testing and more accurate detection of deepfakes. They are responding to a call from the Ministry of the Interior.

Anton Firc from FIT BUT first started to address the issue of deepfakes in his master's thesis, in which he investigated the resistance of voice biometrics to deepfakes. The same issue was then followed up by Daniel Prudky's research, which sent voice messages to 31 respondents and investigated their ability to detect deepfakes in ordinary conversation. "People were told a cover story about the user-friendliness of the voicemails being tested. He included one deepfake recording in the test conversations and monitored the respondents' reactions. The results showed that none of them experienced a fraudulent deepfake message," Firc explains.

However, in the same experiment, when respondents were told that one of the voicemails was a fake, they were able to identify it with almost 80% accuracy. "But the research showed that although a deepfake recording is easily identifiable among real ones, no one can detect it in a normal conversation," Firc adds. Part of the reason for this, he says, is that the interviewer didn't expect it in the context, and that's what the creators of deepfake recordings can exploit in reality.

More than a thousand applicants came to the December and January FIT Open Days

The decision to study at university is not an easy one. There are many questions in one's mind. Is IT the right choice for me? Will I find a meaningful job afterwards? Will I like my chosen school? Will I move to another city for it? At FIT we are well aware of this and that is why we try to make this process as easy as possible for our potential future freshmen by letting them see behind the walls of our faculty, soak up its atmosphere, meet members of the Student Union of FIT BUT and get authentic information and answers to all the questions from the most responsible - current FIT students. 

Every year we organize an Open Day on two dates. The current editions were held on 19 December 2023 and 26 January 2024 with a total attendance of more than 1100 visitors. The DOD program is designed to show our faculty in all its forms to prospective students. An introductory lecture will familiarize them with studying at FIT and the admissions process, FIT students will give them a tour of the faculty and show them our laboratories, and they will also have the opportunity to visit the stands of corporate partners or visit the student club U Kachničky and ask questions about anything that interests them in connection with the Faculty of Information Technology.

We are very pleased with the positive feedback on both DODs and hope to continue to meet many of their visitors in new roles.

Donate to help the families of the victims, crisis assistance and other information from BUT

We bring you information about the actions and measures taken by Brno University of Technology after yesterday's tragic events at the Faculty of Arts, Charles University.


Let's help people affected by the tragedy at Charles University

The Charles University Foundation announces a fundraiser to support the families of the victims, teachers and students affected by the shooting at the Faculty of Arts of Charles University.

All funds raised will be used to provide targeted assistance to those affected by this tragedy.

BUT also participates in sharing and supporting the collection.


Psychological and crisis assistance

Police psychologists organise help for people affected by the attack and their families. Crisis intervention is also offered by Charles University itself by phone or online chat - complete information is available on the university's website.

We recommend downloading Don't panic!!! app (Nepanikař in Czech), developed by BUT students, which provides first aid in case of psychological problems. Their online counselling service is also available. App is available on Google Play and Apple Store.


BUT analyses security measures

On Thursday afternoon, immediately after being informed about the situation at the Faculty of Arts, the management of BUT ordered an immediate analysis of security control at the university. "Although the predictability of similar acts is very limited in real terms, we must deal with security measures that will at least adequately prevent similar situations and enable us to manage crisis situations in terms of increased attention to signals and reports of possible non-standard events, alertness, the ability to secure the area and evacuation," said Ladislav Janicek, rector of BUT.


Expression of support for Charles University

The Rector of BUT Ladislav Janíček is in personal contact with the Rector of the Charles University Milena Králíčková and expressed his deepest condolences on behalf of the University and offered full support and assistance from BUT. Representatives of the university's management and students are communicating and coordinating all assistance through the Czech Rectors' Conference and the Student Chamber of the University Council.

The Rector of the University, together with other Rectors of Czech universities and representatives of university students, attended the commemoration ceremony in Prague on 22 December at Karolinum. Representatives of the Student Chamber of the Academic Senate of Brno University of Technology attended the commemoration in Brno at the Faculty of Arts of Masaryk University together with other student representatives of Brno universities.

We will keep you informed about further progress and steps that await Czech universities in connection with this tragic situation.
