Client-side, or local, storage is an area of concern for privacy and security. Therefore I was keen to attend the latest meeting of the London Web Performance Group titled HTML5 and Localstorage - Storage in the Browser at the Lamb Tavern (building c1780, but on the same site since 1309) in Leadenhall Market on Wednesday evening.
I almost changed my mind as I was also tempted to attend another local event on the same evening about NoSQL for Java Developers. Anyway I was very pleased I went to the client-side storage event, but it was so well-attended I almost did not have a seat. As usual, Stephen Thair (@TheOpsMgr) had done a great job organising the event.
I think users of client storage will have to be careful if it might be determined to be tracking technology. In the FT.com application case, this client storage is not offered to casual web site users, but only to those who have installed the app, are registered and log in. Thus there are opportunities to obtain consent, over and above any warning the device may offer. We are expecting to hear more about the ICO's plans for enforcement of the new regulations at a press conference this morning. Other HTML5 security issues are of course still a concern here. I was slightly troubled by one feature mentioned.
The presenter's slides are now available.
