I have written a number of times on dealing with death and the relationship to your digital footprint

Rule 31 from my 31 new social rules for living in a digital age is about finding someone you trust to ensure that your digital estate can be managed.  Digital Estate Planning appears to be growing   AssetLock.net, Legacy Locker, Deathswitch.com  and

My Webwill  aim to address the issues raised  by enabling online users to securely store online information like logins and passwords to be passed on to relations after death - however you need to tell someone and  Excel does work as a cheap alternative.

On a related but different slant there is E-Tomb which is a solar powered tomb with bluetooth to enable relatives to visit your online profiles and memories after you passed away.

Changing name may be only way to escape previous online activity reports Carrie-Ann Skinner of PC Advisor

“Young web users may be need to change their names when they become adults in a bid to distance themselves from content previously posted online about them” Google CEO Eric Schmidt told the Wall Street Journal: "I don't believe society understands what happens when everything is available, knowable and recorded by everyone all the time." "I mean we really have to think about these things as a society. I'm not even talking about the really terrible stuff, terrorism and access to evil things."

Schmidt also told the newspaper the search engine is "trying to figure out what the future of search is".

"I mean that in a positive way. We're still happy to be in search, believe me. But one idea is that more and more searches are done on your behalf without you needing to type."

He says that at present "we know roughly who you are, roughly what you care about, roughly who your friends are". The search engine also knows your location, which according to the WSJ, means if you need milk and there's a place nearby to get milk, Google will remind you to get milk.

"I actually think most people don't want Google to answer their questions. They want Google to tell them what they should be doing next."

However, social media consultant Suw Charman-Anderson told the BBC, the problem was not as great as Schmidt believes. "There's always a lag between the introduction of new technology and the development of a set of social norms around the behaviour that the technology encourages."

She said the idea that everything is stored online is not true and it will be quite some time before that can become true "because of the enormity of the internet".

"As a society, we are just going have to become a bit more forgiving of the follies of youth."

However, many women are now considering keeping their maiden names rather that changing to their husbands to maintain their professional digital reputation, I suppose it all depends what you need to hide !

Tending to Your Digital Remains is a dead interesting post on a topic I have asked the same question about – what happens when you die.

First you need to make sure you hand on the keys (passwords)

At least three companies — AssetLock.net, Legacy Locker, and the charmingly named Deathswitch.com — have arisen to keep customers’ passwords, usernames, final messages, and so on in a virtual safe-deposit box. After you’re gone, these companies carry out last wishes, alert friends, give account access to various designated beneficiaries, and generally parse out and pass on your online assets. Digital remains that are not bequeathed to an inheritor are incinerated, closing the book on PayPal accounts, profiles, even alternate identities (especially alternate identities: You don’t want your mother knowing about, or worse, playing, the wife-swapping giant badger you became in Second Life).

A second post on the same topic is Logging out after snuffing out  - which is much more about what happens to your digital data, domains and do you want appoint a digital executor to take care of online assets after death?
