The value of online fraudulent transactions is expected to reach $25.6bn by 2020, up from $10.7bn last year. This means that by the end of the decade, $4 in every $1,000 of online payments will be fraudulent, according to a study from Juniper Research.

Mobile network operators will generate an additional $700m annually by 2020 from new universal log-in and mobile identity services - from a base of just $20m this year, according to Juniper Research.

New data from Juniper Research has revealed that global e-retail sales are expected to reach $1.7tr this year, up by more than 17 percent on 2014's total.
