Now he reveals the mixed messages that have come out from LG about precisely what its data collection was for, and how it conflicts with the company's own corporate video.
If you have an article that you'd like to share on grahamcluley.com, please do get in touch.
Last week, it was revealed that Smart TVs made by LG were transmitting details of viewing information and the names of private media files stored on removable USB volumes.
LG released a statement to the press on Thursday stating that they would release an update to all affected Smart TVs to prevent these data leaks and to ensure that viewing information will not be transmitted if the user knows how to opt out.
LG's statement also concerned the use to which the viewing information is put.
Information such as channel, TV platform, broadcast source, etc. that is collected by certain LG Smart TVs is not personal but viewing information. This information is collected as part of the Smart TV platform to deliver more relevant advertisements and to offer recommendations to viewers based on what other LG Smart TV owners are watching.
Interestingly, it now retracts details of how viewing information is used, removing the claim that it was used to "deliver more relevant advertisements".
LG does not, or has ever, engaged in targeted advertisement using information collected from LG Smart TV owners. Information such as channel, TV platform, broadcast source, etc. that is collected by certain LG Smart TVs is not personal but viewing information. This information is collected to offer recommendations to viewers based on what other LG Smart TV owners are watching.
The change in the official statement appears, to my eyes, to be something of a fumble.
As I reported in my original blog post on this issue, LG produced a rather creepy corporate video about how their data collection could help potential advertisers.
Unfortunately, since the privacy debacle unfolded, LG has taken down its Smart Ad website "for maintenance".
However, as you can see in the following video from Graham Cluley, it hasn't prevented the internet from digging out old copies of the corporate video, revealing what LG may have been planning.
LG Smart Ad analyses users’ favourite programs, online behaviour, search keywords and other information to offer relevant ads to target audiences. For example, LG Smart Ad can feature sharp suits to men, or alluring cosmetics and fragrances to women.
So what do we know factually about this advertising and how it relates to data collection?
Very little as it turns out.
It’s impossible to prove with certainty that ad impressions are selected based on detailed lifestyle indicators (as LG's own promotional video appeared to claim) or simply generated at random.
It would be possible to obtain, via testing, a statistical confidence level of the extent of correlation between the ads served and viewing data but LGs platform is dynamic and subject to being updated at any time.
What I can recommend, however, is that LG Smart TV users check that their own TVs have disabled the option - if they feel as uncomfortable as I do with manufacturers snooping on what they're watching.
