Tesco has confirmed it is making changes to its website's systems, following claims that it was putting users' personal data at risk due to inadequate password security.
Tesco confirmed the unspecified changes to its IT systems will be made in the near future, in a statement sent to V3 on Wednesday.
"We review our systems on a regular basis and look to update them if necessary" said a Tesco spokesman.
"Following feedback from some of our customers, we will be updating the measures we already have in place in the coming weeks."
The announcements comes after the Information Commissioner's Office (ICO) said it is planning on investigating the complaints levelled at Tesco, although the firm said it has not received any correspondence from the ICO.
"We have not had any contact from the ICO. We would of course cooperate fully with any requests they may have," added the spokesperson.
The ICO's enquiries follow on from Australian security professional Troy Hunt's accusations that Tesco's website allows shoppers' sessions to be hijacked due to failings in the website's security during a user's sessions.
"Tesco continually overstate their security prowess while clearly under-delivering in their execution," Hunt said in a blog post.
"Clearly the passwords aren't hashed at all let alone salted. At best they're encrypted."
If found to be mishandling customers' data by the ICO Tesco could be hit with a fine. The ICO currently has the power to hand out fines of up to £500,000, though in the past the office has shied away from utilising the full force of its powers.
Most recently the ICO fined St George's NHS Trust in London £60,000 after it sent sensitive medical records by post to the wrong address, and landed a Torquay health trust with a £175,000 fine after it inadvertently published equal opportunity data about its staff on its website.
