The charity has approached a number of undisclosed digital agencies about the brief, which will see the successful shop produce online advertising and a microsite promoting the campaign.
"Dignity" is Amnesty's latest drive to reduce world poverty by campaigning for economic and social rights.
The campaign seeks to highlight the fact that poverty is not simply about a lack of income, but also the denial of the resources, capability, security and power that people need in order to live with dignity.
Rather than appointing agencies on a retained basis, Amnesty tends to pitch its digital briefs project-by-project.
In December last year, the charity appointed Quiet Storm and the digital agency Zerofee to launch a campaign under its "Counter terror with justice" banner.
That campaign was launched in the US to coincide with the seventh anniversary of the opening of Guantanamo Bay.
