Previously verification process were based on sending a code by SMS, but now Twitter created a strong authentication system which becomes more flexible with an alternative method based on an encrypted identification key, stored in the mobile application.
The current methodology is based on the input username / password and communication in a second time interval, a temporary PIN will be sent by SMS to the mobile phone user. This additional layer of security block connections made from a new terminal, including different geographical area or unusual IP. However, it’s more restrictive and this technique has the advantage of involving a physical factor, namely a mobile phone, harder to hack a software auditor as a virtual keyboard. But there are some constraints, especially in terms of network availability and pricing of communications abroad, which can interfere with the reception of an SMS.
Twitter draws its alternative system based on an encrypted identification key, stored in the same application. When the user connects from an unknown device, a prompt notification will be sent to approve or reject the connection requests. Google Authenticator, the tool is dependent on an Internet connection (no offline code generator), but it has the advantage of operating without any restrictions imposed by telecom operators. However, it is likely that eventually the current two-factor authentication methods will give way to an essentially physical dimension in securing the current connections. To overcome the weakness observed in electronic certificates, we can think of RFID tags, the SmartCard and fingerprint readers.
Nielsen, a leading global information and measurement company of Dutch origin, tends to show a causal relationship between television and social audiences.
The group has conducted an independent study based on analysis of 221 minute by minute series broadcast during prime time on different TV channels and changing the number of tweets related to the same series. Thus nearly 48% of the episodes on television followed by the study shows their tweet rates increased according to the television audience. Conversely, the volume of tweets associated with episodes has given influenced to the TV audience in 29% of cases. Paul Donato, director of research at Nielsen, says that there is a mutual influence between the TV audience and Twitter.
“Through the analysis of time series, we saw a statistically significant causal influences indicating a spike in TV ratings can increase the volume of tweets, and conversely, a peak in Tweets can increase TV ratings ”
This interplay is thus very high in the context of reality programs (44% of the emissions studied). Then there are the comedies (37%), sports programs (28%) and finally the dramas that show the lowest score (18%). These tweets exchanges will in turn capture a new audience who are driven by the discussions on the social network will begin to look at this video content. By using these results, Nielsen hope to demonstrate the effectiveness of the measurement solution comparative hearing SocialGuide Intelligence, used in the study.
“The media and advertisers have begun to invest in social networks in order to get closer to consumers directly.
We believe there are significant opportunities for Nielsen to conduct additional research that will, in time quantify the relationship between television and social media activity. “Concluded Paul Donato.
