It's taken a long time，but people have finally discovered how much information companies like Google and Facebook have on them．We cannot keep sacrificing our privacy and dignity to continue using the Internet．However，at the same time，new digital innovations that millions love and enjoy require our data．So what are we to do？
    The biggest issue with the software industry's data collection is the span of time for which it stores information．The industry simply does not believe in a delete button．For instance，Google has records of all my locations for the last six years and Facebook has my deleted messages from nearly 10 years ago．This kind of long-term data storage may seem harmless to some．To others，it may even be useful to know what exactly they were doing on a specific day many years ago，or recover messages from a loved one，or see low much their searching and browsing habits have changed over time．
    However，as government surveillance （監(jiān)視） is emerging as a growing concern especially in surveillance states-the long-term data storage enacted （實施） by all of the top tech companies is a dream come true for any current or future arbitrary government．A 2013 study surveying US writers found that after they learned of the NSA's mass surveillance programs，one in six avoided writing on a topic they thought that would subject them to any kind of surveillance，and a further one in six seriously considered avoiding controversial topics．
    This is why we need online privacy：we have the right to be curious or conduct digital actions without constantly being tracked，or fearing future reprisals （報復）．As Edward Snowden has put it： "Ask yourself：at every point in history，who suffers the most from unjustified surveillance？It is not the privileged，but the vulnerable （弱勢群體）．Surveillance is not about safety．It's about control．"
    The world is constantly changing．It may be too difficult or even impossible to stop some agencies from monitoring your internet activity，but we can at least take a first step and protect ourselves from any potential or future surveillance．They will not have access to your life's diary at the click of a button，or see everywhere you have been for 10 years，or use searching or browsing history from when you were a teenager to question your character．
    This Digital Expiry Date offers companies the benefits of getting your data，personalizing results and still making profits，while putting some control in the user's hands．You will not have to worry about governments or companies in the future mishandling years' worth of information which would limit the damage they could do．A Digital Expiry Date would maintain online innovation and profitability，while helping to prevent any future privacy disasters．
