Google, BT and other leading internet firms have been summoned to a meeting on web safety organised by the UK government.
The coalition is demanding a clampdown on harmful content online, such as images depicting child abuse and material designed to promote terrorism, BBC News reports.
Culture Secretary Maria Miller spoke of widespread public concern over such issues in a letter to the companies, who will attend a meeting on June 17 to discuss solutions.
She wrote: "Whether these concerns focus on access to illegal pornographic content, the proliferation of extremist material which might incite racial or religious hatred, or the ongoing battle against online copyright theft, a common question emerges: what more can be done to prevent offensive online content potentially causing harm?"
The Department of Culture Media and Sport (DCMS) will discuss proposals for a set of industry-wide protocols for tackling harmful content, the potential use of online filters to block said content, and measures for policing public WiFi.
Web giants such as Google, Yahoo and Microsoft could also be asked to consider agreeing to a code of practise similar to the one governing mobile broadband companies.
