- Governments need to do more to ensure they preserve trust as they put more services online, says a report.
Emerging from a European Commission project, it warns that technology could lessen the trust governments have instilled in citizens before now.
Officials must move beyond security measures to reassure people about how they are being treated, it said.
The report comes as the UK government tries to reassure Britons after losing data records for 25 million people.
The report was written by a research body, bankrolled by the EC's Information and Society Unit, that is looking at "citizen-centric" e-government.
The cc:eGov unit points out that increasingly technology, often in the form of websites, is the means by which citizens encounter local and central government.
Frank Harris, author of the report, wrote: "People learn to trust others through experience, and through judgement based on both direct and referred experience."
The danger, he warned, was that these interfaces did not engender the same feelings of trust that have emerged via more traditional routes.
He added that to engender trust in electronic channels required much more than the basic requirements of security.
