Inherent Flaws in Login Systems of Facebook and Twitter with Mobile Numbers

Abstract

There are many social networking websites that provide online networking opportunities; all of these platforms require creating an account, then logging in and updating information to maintain a profile. Our research investigates mobile number based log in feature of both Facebook and Twitters - two exemplary social networking sites – for degree of seamlessness and other security features. Our research reveals that there are major dissimilarities as well as flaws in the deployment of mobile number based login on these two platforms. It has been observed that Twitter allows creation of multiple accounts using one single mobile number, however, logging out from one such account automatically logs out all other accounts associated with the same number. On the contrary, Facebook allows creation of multiple accounts using one single mobile number without deactivation of the previously created ones, however, if same password is used for more than one accounts associated with the same number, only one account can be accessed at any given time. This paper also provides probable solutions to address the security loopholes as identified by our research.

The Proposal of Countermeasures for DeepFake Voices on Social Media Considering Waveform and Text Embedding

“…The generated voice used in our study was produced using the VITS model, as referenced in [39]. We employed a pretrained model from the LJ Speech dataset, which is a publicly available speech dataset comprising 13,100 short audio clips featuring a single speaker reading passages from 7 nonfiction books, as documented in the providers page 7 . Each audio clip is accompanied by a corresponding transcription, with clip durations www.aetic.theiaer.org ranging from 1 to 10 s, totalling approximately 24 hr of speech data.…”

“…We can verify the information by checking the spreader's details. However, given the security issues of social media platforms [7], there is also concern that DeepFakes could be sent through account hacking. In general, with TTS, it is easier to obtain the voice than with VC because it does not require the attacker's voice as input.…”
