A news.com.au report said the Australian Competition and Consumer Commission was investigating Oracle's allegations that data worth as much as $580 million was being used by Google to secretly track Australians' activities.
The Oracle researchers said Google was using about 1GB of data from the accounts of Android phone users, snooping on users silently and collecting data for advertising purposes. They made the disclosures to the ACCC as part of the digital platforms inquiry being conducted by the organisation.
Open enmity between Oracle and Google stretches back to 2010 when the database giant sued the search engine behemoth shortly after it purchased Sun Microsystems and became the owner of Java, claiming that Google had violated its copyright and patents.
The report worked out the cost of the data by calculating that one GB of data costs between $3.60 and $4.50 and multiplying that by 10 million, the number of Australians who own Android phones.
It said the Oracle experts had claimed that the snooping went on even if the mobile had no SIM or if aeroplane mode was on. Only switching off the phone stopped the snooping.
Among the data gathered were barometric pressure readings to determine the height at which an individual was, in order to work out if one was at a certain floor of a shopping complex. This, when combined with location co-ordinates, would allow Google to work out which shops the user had visited, which meant store visits could be tied to viewing online ads.
ACCC chairman Rod Sims was quoted in the report as saying his people were looking into the Oracle claims.
He said the information was "extremely interesting".
“The more we get into this inquiry the more we realise there are lots of issues (around) competition and privacy,” he added.
The report said a Google spokesman had refused to answer specific questions, without detailing what the queries were. But it said the spokesman had claimed that users could see what data was collected if they went to the My Account tab in Settings and they could also control it.
He added that one could choose not to opt in to location sharing and claimed Oracle’s presentation was “sleight of hand”.
