Cuando los usuarios asumen identidades persistentes, aunque sólo se trate de un número aleatorio como un identificador de sesión, existe el riesgo de que el proveedor de red o un atacante puedan observar cómo se conectan los usuarios y la cantidad de mensajes que envían.
</p>
<p>
A continuación podrían correlacionar esta información con las redes sociales públicas existentes y averiguar las identidades reales de los usuarios.
</p>
<p>
Incluso con las aplicaciones más privadas que utilizan los servicios de Tor v3, si habla con dos contactos a través de un mismo perfil se puede probar que estas están conectados con la misma persona.
</p>
<p>
SimpleX protege frente estos ataques al no disponer de ID de usuario por diseño. Y si usa el modo incógnito, tendrá un nombre mostrado diferente por cada contacto, evitando cualquier dato compartido entre ellos.

<p>
Muchos usuarios se preguntan: <em>si SimpleX no tiene identificadores de usuario, ¿cómo puede saber dónde entregar los mensajes?</em>
</p>
<p>
Para entregar los mensajes, en lugar de los identificadores de usuario utilizados por todas las demás plataformas, SimpleX usa identificadores por pares anónimos y temporales de colas de mensajes, independientes para cada una de sus conexiones — no hay identificadores a largo plazo.
</p>
<p>
Usted define qué servidor(es) se usan para recibir los mensajes; sus contactos — los servidores que se usan para enviar los mensajes. Es probable que cada conversación use dos servidores distintos.
</p>
<p>
Este diseño evita que se filtren metadatos de usuario a nivel de aplicación. Para mejorar aún más la privacidad y proteger su dirección IP, puede conectarse a los servidores de mensajería a través de la red Tor.
</p>
<p>
Los perfiles de usuario, contactos y grupos sólo se almacenan en los dispositivos cliente; los mensajes se envían con cifrado de doble capa de extremo a extremo .
</p>
<p>

Muchas grandes empresas usan la información de con quién está conectado para calcular sus ingresos, venderle productos que realmente no necesita y determinar su precio.
</p>
<p>
Los minoristas en línea saben que las personas con menos ingresos son más propensas a hacer compras urgentes, por lo que pueden cobrar precios más altos o eliminar descuentos.
</p>
<p>
Algunas compañías financieras y de seguros usan gráficos sociales para determinar primas y tipos de interés. A menudo eso genera un mayor desembolso a personas con menos ingresos — se conoce como <a href="https://fairbydesign.com/povertypremium/" target="_blank">"prima de pobreza"</a>.
</p>
<p>
La plataforma SimpleX protege la privacidad de sus conexiones mejor que cualquier alternativa, impidiendo por completo que su gráfico social esté disponible para empresa u organizaciones. Incluso cuando se usan servidores proporcionados por SimpleX Chat, desconocemos el número de usuarios y sus conexiones.

No hace mucho que vimos cómo las principales elecciones eran manipuladas por <a href="https://es.wikipedia.org/wiki/Escándalo_Facebook-Cambridge_Analytica" target="_blank">una reputada consultora</a> que usaba nuestros gráficos sociales para distorsionar nuestra visión del mundo real y manipular nuestros votos.
</p>
<p>
Para ser objetivo y tomar decisiones independientes Usted necesita controlar su espacio de información. Sólo es posible si usa una plataforma de comunicación privada que no tenga acceso a su gráfico social.
</p>
<p>
SimpleX es la primera plataforma que por diseño no tiene identificadores de usuario, protegiendo así su grafico de conexiones mejor que cualquier alternativa conocida.

Todos deberían preocuparse por la privacidad y la seguridad de sus comunicaciones — las conversaciones inofensivas pueden ponerle en peligro incluso aunque no tenga nada que ocultar.
</p>
<p>
Una de las historias más estremecedoras es la experiencia de <a href="https://en.wikipedia.org/wiki/Mohamedou_Ould_Slahi" target="_blank">Mohamedou Ould Salahi</a> descrita en sus memorias y plasmada en la película The Mauritanian. Fue internado en la prisión militar de Guantánamo sin juicio previo, donde fue torturado durante 15 años tras una llamada telefónica a su pariente en Afganistán, bajo sospecha de estar implicado en los atentados del 11-S a pesar de que vivía en Alemania desde hacía 10 años.
</p>
<p>
Personas corrientes son detenidas por lo que comparten en Internet, incluso a través de sus cuentas "anónimas" e <a href="https://www.dailymail.co.uk/news/article-11282263/Moment-police-swoop-house-devout-catholic-mother-malicious-online-posts.html" target="_blank">incluso en países democráticos</a>.
</p>
<p>
No basta con usar mensajería cifrada de extremo a extremo, todos deberíamos utilizar las aplicaciones de mensajería que protegen la privacidad de nuestras redes personales y con quién estamos conectados.

A diferencia de otras plataformas de mensajería, SimpleX no tiene <strong>identificadores asignados a los usuarios</strong>. No se basa en números de teléfono, direcciones en dominios (como es el caso del email o XMPP), nombres de usuario, claves públicas o incluso números aleatorios para identificar a sus usuarios — nosotros desconocemos cuántas personas utilizan nuestros servidores SimpleX.
</p>
<p>
Para enviar mensajes, SimpleX utiliza <a href="https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier">direcciones anónimas por pares</a> de colas de mensajes unidireccionales, separadas para mensajes recibidos y enviados, y normalmente a través de servidores diferentes. Utilizar SimpleX es como tener <strong>un correo electrónico “desechable” o un teléfono diferente para cada contacto</strong>, pero sin las complicaciones que implicaría gestionarlos.
</p>
<p>
Este diseño protege la privacidad del que se está comunicando con Usted, ocultándolo a los servidores de la plataforma SimpleX y a cualquier observador. Para ocultar su dirección IP a los servidores, puede <strong>conectarse a los servidores SimpleX a través de la red Tor</strong>.

SimpleX Chat almacena todos los datos de usuario únicamente en los dispositivos cliente usando un <strong>formato cifrado y portable de la base de datos</strong>, la cual puede ser exportada y transferida a cualquier dispositivo compatible.
</p>
<p>
Los mensajes cifrados de extremo a extremo (E2E) se mantienen temporalmente en los servidores relay SimpleX hasta que se reciben, y después son borrados permanentemente.
</p>
<p>
A diferencia de los servidores de redes federadas (correo electrónico, XMPP o Matrix), los servidores SimpleX no almacenan cuentas de usuario, sólo retransmiten mensajes, protegiendo así la privacidad de ambas partes.
</p>
<p>
No hay identificadores ni texto cifrado en común entre el tráfico de servidor enviado y el recibido — si alguien lo está monitorizando, difícilmente podría determinar quién se comunica con quién, incluso si el protocolo TLS se ve comprometido.

Puede <strong>usar SimpleX con sus propios servidores</strong> y aún así comunicarte con personas conectadas a los servidores preconfigurados y proporcionados por nosotros.
</p>
<p>
La plataforma SimpleX utiliza un <a href="https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md" target="_blank">protocolo abierto</a> y proporciona <a href="https://github.com/simplex-chat/simplex-chat/tree/stable/packages/simplex-chat-client/typescript" target="_blank">SDK para crear chatbots</a>, permitiendo implementar servicios con los que los usuarios pueden interactuar mediante las aplicaciones SimpleX Chat — esperamos conocer qué servicios SimpleX puedes crear.

Los protocolos y aplicaciones de mensajería <a href="https://en.wikipedia.org/wiki/Peer-to-peer">P2P</a> presentan varios problemas que los hacen menos fiables que SimpleX, más complejos de analizar y más vulnerables a varios tipos de ataques.
</p>
<ol style="list-style: auto; padding-left: 1em;">
<li>
Para enrutar mensajes las redes P2P se basan en alguna variante de <a href="https://es.wikipedia.org/wiki/Tabla_de_hash_distribuida">DHT</a>. Los diseños DHT tienen que equilibrar la garantía de entrega con la latencia. SimpleX ofrece mayor garantía de entrega y menor latencia que P2P, ya que un mensaje puede transmitirse en paralelo y de forma redundante a través de varios servidores elegidos por el destinatario. En las redes P2P el mensaje se transmite secuencialmente por <em>O(log N)</em> nodos, usando nodos elegidos por el algoritmo.
</li>
<li>
Por diseño SimpleX, a diferencia de la mayoría de las redes P2P, no tiene identificadores globales de usuario de ningún tipo, ni siquiera temporales, y sólo usa identificadores temporales por pares, lo que proporciona un mejor anonimato y protección de los metadatos.
</li>
<li>
P2P no resuelve el problema del <a href="https://es.wikipedia.org/wiki/Ataque_de_intermediario">ataque MITM</a> , y la mayoría de las implementaciones existentes no utilizan mensajes fuera de banda para el intercambio inicial de claves. SimpleX utiliza mensajes fuera de banda, o en algunos casos conexiones seguras y de confianza preexistentes para el intercambio inicial de claves.
</li>
<li>
Algunos proveedores de Internet pueden bloquear implementaciones P2P (como <a href="https://en.wikipedia.org/wiki/BitTorrent">BitTorrent</a>). SimpleX es independiente del transporte, puede funcionar con protocolos web estándar como por ejemplo WebSockets.
</li>
<li>
Todas las redes P2P conocidas pueden ser vulnerables al ataque <a href="https://es.wikipedia.org/wiki/Ataque_Sybil">Sybil</a>, porque cada nodo es susceptible de ser descubierto y la red funciona como una unidad. Las medidas de mitigación conocidas requieren un componente centralizado o bien <a href="https://en.wikipedia.org/wiki/Proof_of_work">pruebas de trabajo</a> costosas. La red SimpleX no tiene capacidad para descubrir los servidores, está fragmentada y funciona como múltiples subredes aisladas haciendo imposibles los ataques a toda la red.
</li>
<li>
Las redes P2P pueden ser vulnerables al <a href="https://www.usenix.org/conference/woot15/workshop-program/presentation/p2p-file-sharing-hell-exploiting-bittorrent">ataque DRDoS</a>, donde los clientes pueden retransmitir y amplificar el tráfico, provocando una denegación de servicio en toda la red. Los clientes SimpleX sólo retransmiten el tráfico desde una conexión conocida y no pueden ser utilizados por un atacante para amplificar el tráfico en toda la red.
