Collaboration between schools at a cross-national level requires a secure and trustable system that respects the rules, and policies of the parties, specifically the General Data Protection Regulation(GDPR) needs to be placed in the system. The GDPR, or similar laws and the curricula differ in respective. Students who want to take any course at another school abroad cannot easily sign in and access the study content, even if that school wishes to share it. Still, this is what society, industry, and education ministries in different countries wish. The schoolgirls in Afghanistan who wish to study online in the girl's school of Ireland are specifically considered as a case study in this paper. We use a case study research method in which the existing online learning tools are analysed that are used in Irshad High School in Afghanistan and Coláiste Nano Nagle School in Limerick, Ireland. We furthermore prototype the architecture of a system that provides a secure collaboration platform. Thus, this collaboration platform we develop can be adopted at various levels of education for any country with the goal to achieve a longterm effect on the flexibility of the respective education systems to yield a globalization of education. We use the internet, mobile and educational platforms, and a secure broker (interface) that provides the tools for the schools' collaboration, including the sharing of resources, an exchange of experience and enabling access to education worldwide.
