Gigya therefore cites the big challenges for identity management as follows:
1) User Experience : Legacy IAM solutions focus on security. Current CIAM solutions focus on sharing the identity across businesses.
2) Scale: While identities explode for a single individual, employee, partner or vendor, performance is maintained across levels by scaling out
3) Data structure: The vast majority of customer generated information is unstructured and requires new analytics and pipeline capabilities.
4) Integrations: This is perhaps the single biggest development cost for today's CIAM solutions as companies not only integrate with business applications but also with customer facing applications and activities.
5) Security: WebAPIs and open protocols have required changes in the way identity information is persisted and propagated. Authentication, Authorization and Auditing have taken new forms
6) Privacy and Compliance: While regional and international regulatory compliance have to be complied with, customers are requiring social networking integrations which make these tasks harder. Security breaches alone can undermine the entire CIAM solution
CIAM Solutions can be either homegrown or purchased. They differ from IAM solutions in these ways :
1) less infrastructure CIAM is cloud based
2) licensing is based on users or login and not servers
3) support and maintenance is less as it is part of the service
4) deployment time is reduced
5) backend application integration is faster and with fee only per application
6) Customer experience customizations can be improved out of band

Find four distinct integers a, b, c, and d such that each of the four sums a+b+c, a+b+d, a+c+d and b+c+d is the square of an integer. Show that infinitely many quadruples (a,b,c,d) with this property can be created.
We can denote the four sums as squares w, x, y and z
therefore a = (w+x+y+z)/3-z
b = (w+x+y+z)/3-y,
c = (w+x+y+z)/3-x
d = (w+x+y+z)/3-w
In order for a,b,c, and d to be integers we only need to have the sum of the squares w+x+y+z to be divisible by three. In order for a,b,c,d to be distinct, the squares must also be distinct, Also, the largest of the squares must also be smaller than half the sum of the other three squares so that the smallest of a,b,c and d will be positive. By trying incrementally, we can see the smallest set is the one satisfying the squares of 8,9,10 and 11.
